Poor Service Fibrestream

I singed up 25 June 2020, I had connection trouble 29 June when the tower went down, I was advised to upgrade which I done on the 1st July, 7 July the high site went down for more than 12 hours and ever since then I have had experineced the worst connectivity ever, lines dropping to 1mbs Download and 0mbs upload. We were searching for uncapped wifi as we do not have fibre to the home in our area of residence. I have been sending emails trying to call the offices to speak to someone regarding cancelling my services with Fibrestream with no luck since 9 July, not even the sales rep or CEO has been responding, I feel helpless and need to get this cancelled.
