Poor client services

I have been a client since last year The last week to 2 weeks I have been experiencing poor internet connectivity I have spent over 3 hours on the phone with them More than 20 phone calls Some being dropped Money on 4g data so I have internet etc Trying everything possible to proof it is not my setup Tested routers Setups Extenders Direct to fibre box Being told issue is logged and then a week later it was not logged Then vuma tel was going to come They never came Everyone telling me the line is up When I do a speed test and a tracert they all show request timed out or not connected or 1 out of 20mb or 6 or 14 etc. Poor internet When I test on the vuma site it shows 20 but at the same time I cant even use google as it is so poor If the ISP is throttling or the line is bad or something Someone has to assist at some point It's been 8 working days now and no one seems to care
