Bad service and closed my account that I've had for years

TFG handed over to pre legal becuase I couldn't pay and I was not well for those months. After paying my account they telling me that I can't use it any more. So TFG doesn't understand that we are human and qe get sick. I ask for the terms and conditions of the agreement that should I not be able to pay my account the will close it know my behalf. I wanted to see if we had an agreement for that. I asked for my contract that I signed and the sent me a 1 page with no terms and conditions that I signed for. Instead they included a link of the terms and conditions that I was not awear of and Nathi cut my call and didn't call me back after I asked him to send me the terms and conditions and they must highlight what they were saying to me, I didn't get that. I ask Gadijah for her manager and that IA qhen she transferred me to a gentleman that called him self Nathi.
