Credit still not passed

I previously posted a complaint on Hello Peter (SM220316), it was closed but the matter is still not resolved. No one has come back to me to tell me when the credits for the December, January and February invoices will be done (which was paid for), as well as the credit that now needs to be done on the March invoice that will be paid via debit order at the end of this month. I also need someone to tell me how I am supposed to upgrade my other contract ***). This is a data contract which I had a laptop on. I can upgrade this in store only - according to the call centre, and there is now Telkom store in Welkom any more. I was told by the call centre that I need to drive through to Bloemfontein to get it done. I will not and cannot drive an hour and a half to Bloemfontein and then a hour and a half back again. What do I do now? If Telkom cannot help me to upgrade that contract, I have no other choice but to cancel my contract. I need someone to assist me in these two matters ASAP!!!
