Poor service from PriceLock and Multichoice

This is my last resort. I have been a DSTV customer for more than 10 years and I have never been dissapointed by their service until now. This morning I was told by a call centre supervisor called Shanani that they are a customer service center and they do not sell stuff and they do not call customers bac**** I app**** for and was approved for PriceLock at the end of Feb 2019. The decoder was supposed to be delivered to me and then I would have to contact my closest installer. I have not received the decoder. The courier reported that he was here BUT I work from home and I have admin staff also and none of them turned a courier away! After 7 phone calls I eventually was called back by Nthabiseng on the 20 March (more than 20days later). She arranged to have my new decoder sent to the the DSTV Center in Centurion and they were going to . Today is the 1 April. I have been calling customer service since Wednesday of last week. 8 calls later. They gave me 2 numbers for Pricelock 011 ********** / ***THEY DO NOT WORK! They keep sending escalation emails to the PriceLock department - no one has called me! 30min ago I asked to speak to a supervisor and was told by Shanani in no uncertain terms that she is at Customer Service and that her department does not sell products and does NOT call people back. "You have to contact them yourself and arrange it." But I cannot call because the numbers do not work!

Please can someone assist me in solving this problem.
