Pathetic service

I did an upgrade on my data contract in Dec 2023. Spoke to Nobuhle. On 8 Jan we have discovered that the upgrade did not take effect due to a system problem. The upgrade was redone. Black Friday special R99 for 5 gig day and 5gig night. I have received my Jan bill for R255. I am being told that I have received 3.5 gig in addition and I have used it. I did not ask for it and was not aware. 2 days ago my data of 5gb day had been used up however I have received another 3.5gb which I did not ask for. I am receiving SMS's about my upgrade again. I was informed by Kamogelo Ramapakela to not use the 3.5 gb which had been allocated to me hence I have removed my SIM. I cannot use the services which I have contracted to and there is a problem that no one can detect. I have taken another contract with another service provider due to this issue as I cannot pay R255 per month and automatically receive extra data and be billed for it. Please cancel my services as you cannot deliver and not fulfilling your part of the contract. I was only supposed to receive 5 gb day and 5gb night. please fix your mess and do not throw this onto me, It clear 5gb day and 5gb night for R99, I am not responsible for any amounts more than R99 and any additional data which I have not requested.
