DSTV Explora offer and service departmen dont get

After requesting a quote on the 20th of January, i had to a call and spoke to 7 people on Friday 23 to have any action taken. The call center super visor eventually resolved my issue within 45 mins. The decoder was delivered on the 27th quite impressive, i phoned the call center to configure my account etc. this was done just to be told my sd pvr that is supposed be extra view will not work as the smartcard is wrong and i need to go to a walk in center but the explora is working. Yet on the morning of the 28th i have no service on the explora again and on calling the call center i am advised they have to swap the explora as it was delivered with the wrong smart card and that my service that as working the previous day cannot be reactivated due to the smart card miss match. When requiring about a complaints department i was told they don't have one amazing how a service provider can get away with something like this.
