Disappointed Customer

I tried to do an online upgrade but received a message that something is wrong with my account. On 27 July I went into a Vodacom store, and they asked me if I am under debt review. I have never been, and all my accounts are in good order. I have 3 Vodacom contracts and Vodacom fiber, all paid diligently. They assured me they will have the block on my account investigated and submitted the upgrade request. After receiving a call from the store, saying all is in order, I checked my account status only to find it was still blocked. I then phoned in and reported the block and checked on the upgrade status. The agent said there was no upgrade requested. He then reported that he submitted the upgrade request. Two days later I checked the accounts status again which I found to still be blocked. Phoned in again. Same story. It is now almost two weeks later and neither request has been fulfilled.
