Telkom mobile - Breach of Contract - No Help

On the 22.2.16 Monday i signed a contract at Telkom The Glen Store, i ported my number through to Telkom also as i obviously needed to. They said i have 7 days to test the network & showed me on a coverage map i have signal at my home. So i signed the contract with (Busi), 2 days later after testing the network i can not make or receive calls in my home. I have to walk outside towards the road to receive or make calls. So on the 24.2.16 Tuesday i went back to the store to get my number back and cancel (i filled in a cancellation form). Well till today i have made 7 visits to the store dealing with the Manager Frans and numerous calls to head office, it's been 2weeks with no signal and my home business is suffering and my only source of income. I have 2 case # logged for the cancellation of my contract # ***3 (This is the stores case No.) & # ***8, (Head Office Case No.). Nothing is being done !.....just making case numbers with no action while my business & i suffer. I havent had any call from Telkom only me that fights at the store and on the phone with head office. I have sent pictures to head office showing my signal problem even. Still no reply. When will this hell end?
