DSTV EXPLORA - Pricelock (Horrible service)

I have app**** for DSTV explora pricelock last year September, got approval same day and got notification that I will get delivery within 2 to 4 working days with a parcel delivery reference number. Until today, no delivery. I have contacted DSTV several times and every time I am told they will investigate/ escalate the matter and give me feedback within 48 hours. 48 hours passes , no response from them. when I contact them again, I need to explain the issue from scratch customers on the system nothing shows that I have made a query or there was an escalation. the reference numbers they give me are not valid. DSTV consultants have very poor service and DSTV seems to be making false advertising with the service they can't provide. I spent 20 minutes with a consultant who was arguing that its impossible that DSTV contacted me regarding delivery but did not deliver and asking how sure I am that the communication was from DSTV , it could have been from other companies. Now that brought even a question of the confidentiality of the personal information provided....how would other companies get hold of my personal information and know that my application with DSTV was approved. when I read out the smses I got she puts me on hold and comes back to say she will escalate and I will be contacted within 48 hours. how many escalations needs to happen before a customer gets assistance? does dstv even have this decoders they are advertising? how could delivery that was supposed to take place within 4 days now taking over 6 months?
