Telkom Please improve your C.R.M and your clients issues

Good Day, I need assistance. For months i have attempted to contact consultants,via email, consumer helpline landlines numbers, bot portals,but to no avail. I have physically been in store to change my debit order dates,as a result of this, my account has been building up penalties due to rejected debit order dates. Now I refuse to pay this if I have not made any form of attempt to resolve this issue. Besides the connection which is half of the month off due to connectivity problems,they have disconnected me because of rejected debit orders,which the system is failing to change. I have to resort to purchashing crazy amounts of mobile data because i do online teaching and now I am losing work because I have no connection. My statements get emailed monthly reflecting all rejected dates,but I cannot reply to the emails as it states a no-reply email and bounces back. Yesterday,Telkom called me which i hastily answered,but it went straight to voicemail. I'm.not sure whether to terminate my contract and get another service provider,but Telkoms rates seem to deem fit financially for me but I cannot pay R520 penalties upon my monthly rate, then I might as well just change service providers and go for a faster mpps line,which I cannot afford. Telkom,please improve your service,please don't be quick to get people to open contracts but never follow up with your client's when there is problems and issues. This is a matter of urgency that I have to resort a platform like this to have problems resolved
