Zero/Zilch aftercare service from MTN

Is been a solid 4 months since I upgraded my contract and received the wrong watch with the package...after several calls, numerous e-mails, a complaint logged with their complaints departments (which is pretty much non-existent) and having logged a compliant with the Consumer Goods & Services Ombud...no response to date to rectify the error, plus they still have the cheek to call me to upgrade my other number.
