pathetic service

My husband and I went to a telkom, cavendish in november. We signed up for a 40G wifi contract. We collected our package at the beginning of december 2015. An hour after activating our wifi we were notified that our data was depleted,we called the call centre. They informed us that we only had a 1G data bundle and not the 40G we signed for. We returned to the branch where they said they will issue us with a new simcard. This only happened four days later. When we collected and signed our contract with telkom we were informed that they would bill us for Dec&Jan together. Our debit order was set for the 1st February, by the 3rd of Feb, no deductions were made from our account. We went back to the store to try and correct this. At the store we were informed that t they had the wrong account number, but the contract that we signed had the correct details. We were then told that the system doesnt recognise us having a contract. I am more then happy to keep receiving free data but I wish to rectify this. I am tired of calling telkom/ going to the store to rectify this matter. I am utterly disgusted and disappointed that telkom runs such a pathetic service and they pay for inefficiency.
