LACK OF SERVICES IN PRETORIA AND BAD CALL CENTER SERVICE

Its been now two weeks since my explorer saying E143 and waiting for primary decoder. Call centre is costly, i called so many times to get assistance and being charged for non-service. Yesterday i called twice and i was told i will receive a callback from technical around 5 or 6 pm, i waited until i slept without any help. What is worse the only pretoria office in centurion was closed and now agencies tell me they don't work on explorers. I am very frustrated by lack of service and terrible treatment as a paying customer. I need services that i am paying for my 4 decoders please.
