Dstv price lock

I was contacted by Dstv price log on 17 September 2019, as I was informed by Dstv account department that my Dstv price log contract expired. After trying to contact the price lock department, they phoned me on 14 October 2019 to inform me that this has been escalated to be resolved. My secondary Dstv is not working, as there is an error 48-32. I phoned Dstv on Sunday 20 October to resolve this problem, but the lady could not assist me, because I was on price lock and according to her the new price lock deal was on the system. I did not even received any hardware and no installation was done. I have been waiting since September for someone to get back to me. On Sunday I was provided with a number to which I must send an sms for the price lock department to contact me, still waiting for a response. My secondary decoder is still not working and Dstv have made no effort what so ever to contact me. This is the price you pay monthly for the exellent service they render
