TELKOM at it again

I was approached by TELKOM Mobile Sales, I thought it was a good deal. I took out the contract when package was delivered at first could not get the modem to work. Drove to the Telkom walk-in Centre at Mall @ Reds. Staff could not assist and I was tasked to call the Call Centre. I called the Call Centre (9/11/2017), they were also not able to assist. I thought to myself let me rather cancel the contract, if this was the type of service that I was going to get (also from my previous experiences to get a contract cancelled after it has expired, I was more convinced than ever that I should cancel). I immediately informed them to cancel the contract and arranged for the device to be picked up. After numerous calls on 9/11, 13/11, 17/11 and 8/12 after my details were taken down, I was promised that I would be contacted to arrange for the device to be picked up. To date almost a month later nothing has been done except me being billed for a device that was supposed to be picked up. Clearly staff are incapable to execute the duties or the brand TELKOM just want to rib people off. How hard can it be to arrange for a package to be picked up? Come on should be as simple as when you made the sale.
