Incorrectly blacklisted phone

Having had an existing Telkom mobile contract, I went in to the Telkom store in Irene to get a new contract in October last year. On the day I did the application for the new contract, the phone on the existing contract suddenly came up saying that it cant connect to the Telkom network. I took the phone to the store the following day. The lady had a look and advised that they should do a sim swap, which I would have to pay for. So they swap the sim, and I pay the R37, only for the problem to continue. They then tell me that they have to send the phone in for repair, but I have to find the proof of purchase for the warranty, as they don't have it on the system(How does Telkom not have the details of contract phones on the useless system!!!). So I first have to go home get all the paperwork, and then drive all the way back to send the phone in. 3 Weeks later the phone comes back, still not working. No feedback on what was done to the phone. I decide to take the phone to the Samsung store in the Grove mall. Three weeks later they get back to me saying that the phone is blacklisted on the Telkom network, it works on other networks! So I go and fetch the phone and take it back to the Telkom store. The Telkom system in the store shows that the phone is not blacklisted, but when they phone the back office it shows that the phone is blacklisted. So after all this driving up and down to get the phone sorted out, wasting my time and money, IT SEEMS THAT THE *********** STAFF AT THE IRENE STORE MUST HAVE ACCIDENTALLY BLACKLISTED MY PHONE, BUT ARE TO USELESS TO OWN UP TO IT!!! Now the real fun starts. I have been trying to get the phone UNBLACKLISTED on the Telkom network since NOVEMBER last year. Countless calls, useless agents who make promises, I don't know how many ITC reference numbers, saying that the phone is no longer blacklisted, and the problem should be fixed and I still cant use my phone!!! I have to use an old phone to get by. THIS IS ABSOLUTELY RIDICULOUS SERVICE!!! DOES NO ONE AT TELKOM KNOW HOW TO UNBLACKLIST A PHONE???
