Disgusting Service - Do not deal with this busines

Telefusion services installed a new DSTV cable to another TV, We lost picture to the other TV's. We called them out to honor the 6 months guarantee. They were rude and not happy to come back. Tried to fool us by stating we have trees blocking our signal. Eventually another company came out and fixed the problem. The other company called Telefusion Services and told them that they blew up our switches. Telefusion Services told us to send banking details to arrange a refund. A week later we called and they threatened us and told us to remove their installation, drop the cables off at the SAPS and then only will they refund us!! Can you believe it. Do not deal with this business.
