Multichoice bad customer service

Bad service received from Multichoice consultants. On the 23rd of July, I received a call from Multichoice offering me an Explora on price lock. Everything was captured and I was told that it will be delivered between 4-7 days. then last week on the 31 I called them requesting assistance cos my device was not delivered the lady who spoke to me was so polite and she said that she will escalate the matter. Yesterday on the 6 August I called again and spoke to one of the supervisors and again he said he'll escalate the matter. today on the 7th it was worse spoke to someone, it seemed like it was her first day at work. she asked me to hold then came back telling me that if I don't have the reference number I'll have to wait, there's nothing they can do. I called again, the call was hanged up and again and again until I decided to write a review. I just dont know who to call now.
