They are robbing customers

I opened an account with the tfg group only received R650 credit. I was in arrears with my account due to circumstances I took their calls in the beginning and explained to them that I will pay my account and yet they still called me more than 10 times a day and I blocked the numbers because I did explain. I'm the meantime they were charging me for calls made but it was unanswered calls my account is now R1056 because of being charged for over a 1000 Unanswered calls. End of February I went to totosports and asked what my installment was they said R250 and I paid it now I must make a payment April and yet they still phoning me everyday letting the phone ring 3 times then put down and yet still charging R20 I please would like them to have a look at the calls made to me and see that I did not answer the calls and to please to remove all the R20 they added
