Bad communication

Still not sorted out. I keep getting messages that my account is handed over but i have made my payment that was discussed with an agent since December. I do not receive calls but get text like that. I have not used data or used the sim, but still they have not corrected my account. First my account was settled for R1600. I paid R1000 already and then R600 mobile payment, now i see the amount is R1700. This is *****.
