PEP Dstv Disconnect

I bought a Dstv at Mitchell's plain on 3/11/18 . The cashier gave me one service provider to contact at ********** . I provided my details to the provider and he promised to come and install the Dstv on the 5/11/18. I called them on the 5th and the 6th to come and complete the sale. To my surprise nothing service as not be finalised and I'm very disappointed.

I think a customer should be provided with at least 3 or more services providers to promote competition, ease the pressure on one service provider. I believe this can be better handle provided that the store manager and his/her subordinate take their job serious and give penalties to their under performing service providers.
