Cell C sadly the worst of the worst

Last week on Thursday evening I went onto the Cell C website and purchased 1.2GB of data and paid through Instant EFT, my payment was successful but my DATA was NOT credited to my cell phone number, I phoned the customer care immediately and was told the payment was not showing and I must WAIT 24hrs before phoning them again. In the interim while having to WAIT which has NEVER EVER happened before, as the data has shown immediately, I contacted my bank, they said the payment had gone through and was out of my account, I then phoned PayFast Cell C's payment gateway service provider, they said my payment had gone through and was paid to Cell C. I then contacted Cell C 24hrs later and was told the payment was not showing on their side and I must now fax through a POP, which I did giving them my cellphone number BOLDLY in the subject line. I have phoned them on numerous occasions since then and still told to WAIT as it is now a QUERY and they will deal with it. Yesterday I phoned them again and some rude and arrogant customer care person began to rattle off how many times they had "TRIED" to phone me, I said this was NOT true as I was the one always phoning them, he then got more arrogant and rattled off my data ONLY number, I said this was the wrong number and the query DID NOT relate to this number and I asked them to sort it out immediately. I then got a call from Cell C but it was some person asking me if I want to UPGRADE, HOW SHOCKING!!! I have still not had an answer to my email after my POP or a telephone call to let me know where my data is, Cell C has my money and I have nothing in return. I have been with Cell C for nearly 20yrs and will now cancel all my contracts with them, their customer service is the worst I have ever had to deal with no-one knows there left from the right!! Goodbye and good riddence Cell C.
