I used to have the same company” Power Net Global” and I had a lot of problems: high taxes, no customer service, changing of rates without notice…..
My friend referred me to another company called PULSE TELECOM .I have for two years this company, and to tell you the truth I am happy; their connection and prices are very reasonable. Their customer service very reliable in other languages also, just in case you have trouble with your English. Make sure that you send them the bill on time because they will charge you a late fee, and you have to call them in order to get rid of it.
