Horrible Service

Last week Saturday R400 package was expiring and I paid a R400 for the next 30 days online an hour before the package expires. After an hour the data switched off, went to check my online account it showed R0 while I received a confirmation email from Metrofibre that my payment was successful and the payment did go out from my account. Sunday it was not allocated, early Monday I called them and was asked to send my bank statement as proof of payment and I did then they promised that it was escalated to the finance department. From Tuesday till now I have used over R400 calling and emailing them to assist allocate my payment as I need this data for work purposes. All the agents keep on saying they will escalate the issue for manual allocation but nothing happens. I went on Twitter and asked for assistance on their inbox, I was promised that it was escalated to the Metrofibre Home agents but nothing has happened. I've spoken to over 8 agents already using my money just to be ignored and given the same excuse. I regret my decision of choosing them. I asked that because they don't want to allocate my payment can they give my money back, no one is willing to assist.
