Waste of my time!!! Worst service.

Worst call center service! Do your Teamleaders even have phones to call clients back? What really happens when a problem is "Escalated?" No one can give me answers. It is a mystery! Been trying to cancel tablet contract for 7 months, waiting for refund for 6 months for when my brand new phone went in for repairs. was not repaired and I literally had to track it down to get it back. This week it took 2 calls to blacklist my phone when I was ******. 20 min waiting time just to get through. Worst decision to move from Vodacom to Telkom, I will not be renewing my contract when it is finished!!!! I even complained to the complaints department 5 times and still no response. They just respond saying they will respond :(
