Pathetic service from DSTV

I contacted DSTV regarding there price lock deal and upgrade to the Explorer 2. My call was taken efficiently and my application including credit check was approved. Unfortunately that is where it ended. It has now been well over a week and no correspondence has been received. I called the helpline and was told that someone would make contact to have this issue resolved. This I was told would take a further 48hrs, well guess what 48hrs have passed and no call has been received. What pathetic service!! DSTV clearly do not need our business.
