Cancellation and ********** contract tempered

Good day I app**** for fibre contract on door to door sales consultant, and I was sceptical to apply to him. Avoiding this problems I have right now . He sold me false adverti*****t and reported the matter several times. He said to me the fibre I am taking is month to month like DStv. Uncapped for 410 special only to find out he **** and then he ticked 604 monthly installment in which we did not agree on. I then did a billing request and investigations and ask them to send me a contract. Only to find out everything I wrote with black and white is my hand writing. And he tempered with blue pen on the term of contract and billing as per our agreement. I relocated gave them month notice of relocation and they said they will cancel the contract. Because where I relocated there is no fibre coverage. 5 months later the matter is not resolved please find all references given of billing , cancellation investigations SR***/SR***/SR***/SR***
