I and my room-mate have been battleing this same issue with ZPDI and our actual service provider, Centurylink for almost 4 months. Our Bill is now at $500.oo and our service is disconnected except for, get this, "INCOMING CALLS". which is no surprise as we began writing down all these weird calls that we began getting weeks ago where someone calls in and when we answer and say "hello" like 3 or 4 times... they then hang up. Funny thing is that we began to notice the pattern that these calls come in at 8.am to 9 a.m and again at 4 p.m. to 5 p.m.. So, we have been writing a log of all these and keep the list next to phone with pen and will be submitting this to our provider and the attorney Generals office as well. I had called Centurylink on 3 differing occasions to ask that Zpdi be blocked from our service and i also requested that any and all collect calls be blocked from our phone service, . And if you read our bill, you will find that we r being charged even for collect call blocking at $5.00 per month, plus the tax there=of. Come on people, what does it take in this country to get some decent service for any of our services? How can my provider tell me that we have to call ZPDI in order to get the charges removed from our bill when the Centurylink company is in essence, allowing this abuse by being the party whom is billing us for these fraudulant charges, forr a scum ass fraudulant company whom it takes you practically an act of congress to get through to any real customer service representative... and once you actually get one onto the phone line 20 mins to a half hour later. they proceed to be sarcastic, snyde and plain rude, while denying that their company has any responsibility in correcting the errors. i have spoken with ZPDI reps on 2 occassions and they said thwey would remove calls from my bill and would futurely block any further use from their services- yet, here came the next monmths billing statement and it had more expensivew charges billed to us this time then ANY other bill.
