I opened a phone account authorizing $100 charge. When I reviewed my credit card statement there where 6 additional charges totaling $363 the next month. When I called requesting information they told me it was from their sister company DSI and that I would need to call them. I told them the charges were listed to them but they would not help me. When I called DSI they said the exact same thing, that I should call Global Tel*Link and request a refund. I have filed a complaint with the FTC and my credit card company has reversed charges pending an investigation. This company is a total RIP OFF with exorbitant fees for adding funds and monthly open account charges. It's a crime that families of inmates have no alternative than these shysters to deal with in a stressful time.
