Disgusted at how Vodacom treats their customers #noTCF

I am so frustrated in the service I am getting from Vodacom, after being mislead in a sales transaction, I have been trying to cancel my contract since. I am not able to cancel the contract until they collect the device and Vodacom has not collected the device. I logged the call 1 month ago. I have called numerous time, sent many emails to customer service and complaints email address, requested that the team leader to contact me and had no luck. Nobody responds and the only response I get when I call is that they will follow up on collection. It will utterly disgusting how you treat your customers
