terrible terrible service

Signal Booster South Africa is the worst online company when it comes to policies and what they maintain of there services towards there customers. We had purchased a signal booster from the online website with a 15 day return on the product. From the time the product arrived we have not heard from Signal Booster SA, we have been trying to get some feedback from them regarding the product in terms of installation nothing we then got another installer he said its a nonsense product, after several communication with signal booster sa to return the product there was nothing. Terrible terrible company.
