Network problems and bad service

I have a contract with Telkom for which I’m paying R1000 pm and yet I have had no network since the end on March 20, my network is 90% down and yet they debit me like clockwork, this has caused duress on my business as my clients are not able to contact me and vise versa, I called them numerous times and they are not able to fix the issue, leaving me no alternative but to cancel my contract and ask them to transfer my no onto pay as you go and I hope they able to at least do that properly as I’ve had this no for over 20 years, Telkom service is Worse than ever and they don’t seem to be in a position to tackle the network problem I’ve had for 2 months it’s ridiculous
