GC 'services' is as slimy, scummy, filthy low-life as you will ever run in to. I ran in to the same thing others did. My ex-wife kept receiving calls from them over a credit card. Reps called 3-4 times/day and were even abominable to the point of finding where I lived and then they kept calling a neighbor who was related to my landlord's daughter! I believe every word you said about them finding and harassing your cousin.
You need to call your local consumer protection agency. If they won't do any thing, call the Commission that regulates telecommunications. Not sure if it's called the State Corporation Commission of MO, TN - where ever. All right. Tell the rep's supervisor what is going on and that you need them to provide you with a recorder that you can hook to your phone. They may not go for it, but it's worth a try. Once you've called one of those regulatroy bodies, call the Attorney General of the state that you live in now. You probably have to prove to them that you have attempted another party, which is why I mentioned the above. Tell them precisely what is going on. They may not or may furnish a recorder for you or a means for them to record when GC hardened criminal calls. You may have to buy a recorder, but it is worth it. You will have to ask around; I don't know how to get a recorder that records without the caller knowing. But I do know it is possible to do. Then you can take these sodomites to court and you will sleep very well knowing you have struck a blow against them. Sodomy is illegal. It is a crime and there have been complaints of sodomites making advances to those of the same sex on the job: Genesis 19, 13:13, Isaiah 3:9, 5:20-23; Ezekiel 8, 18, 23, 1Kings 22:46, Proverbs 10:27, 24:5, 24-25; Romans 1, 1Corinthians 6:9, 1Timothy 1:9-10, Exodus 22:19, Leviticus 20:13, Hebrews 13:4, 2Peter 2:6, Jude 7, Revelation 21:8, 22:15, etc.
Collection agencies are garbage: they have no right to exist. You are assumed to be guilty until proven innocent and they want to give the impression that the alleged charges, fees, etc, are valid. Meantime, I hope your wife is keep a log of the sleepless nights, etc. This will be invaluable to your attorney, if you can find an honest one. Difficult to do. That first Link below has a few posts that may be of some help. Lord Bless.
On that debtconsolidationcare.com website, some sharks were attempting to defend GC services. They can put their money where their mouth is and pay the medical bills and pastoral counseling expenses as a result of what they were put through by fecal eating reprobates who will do any thing for a living - including harass people for 7/hour. Nice to be associated with illegal immigrants, isn't it?
GC anti-services are the lowest, vilest, most heinous gansters! They will drink molten lava and liquid for all eternity. They are to be tried, convicted and stoned until they die and go to Hell!!
Ywn 666, apologist for GC anti-services and posting on the internet: you are a liar!!! Thou shalt not bear false witness. You madam, are worthy of being stoned to death! They harassed me and my ex-landlord's daughter's friend. They don't talk to the debtor as documented by others!!! They are NOT AND NEVER HAVE BEEN A 'LEGIT BUSINESS'!!! Nor can the scum be, because they are in diametric violation of the First Amendment to the Constitution, the Bill of Rights and the spirit of the Constitution of the United States. GC anti-services CANNOT ASK FOR YOUR PRISONER-OF-WAR NUMBER!! They have no right to it under the Constitution and even under Directive 1193, dated Nov 22, 1943.
And as for the employee, you, madam are a liar!! Thou shalt NOT bear false witness. Exodus 20:16, Deuteronomy 5:20. You will burn!! To work for the filthiest, scumiest, slimiest, sodomite unspeakable acts company in the world - I know an awful lot about you!! Your company NEVER, EVER VERIFIES NOR HAS ANY INTEREST AS TO WHETHER THE ALLEGED DEBT IS VALID. YOU ARE A LIAR AND IF WE STILL LIVED IN THE OLD TESTAMENT, YOU, MADAM, WOULD BE STONED UNTIL ALL YOUR BONES BROKE, YOU BLED TO DEATH, AND YOU DIED AND WENT TO HELL!! HEAR THAT?
