MWEB not assisting

I have been a customer of Mweb since 2016. I have recently upgraded my line as I was having issues connecting and with working from home I depend on the line being up. I have called through on numerous occasions and logged call tickets with regards to my line dropping and speed being an issue etc. Today again I am experiencing the same and having to use my mobile data which is now costing me extra. If I call through I am going to be call number 20 something and use my airtime. Please can someone assist urgently with a proper solution.
