MWEB/ Openserve Poor Service

In the last month of having the MWEB Fiber at my house, I have since the first day never had the line speed that I have requested, it has barely been half of the speed requested at any given time of the day. Throughout the month I have made 7 Calls to them each time I end up in a line with an average of 18 callers, waiting for at least 45min to an hour to speak to a support tech. the line is supp**** by Openserve, MEWB never has answers as to why my internet is slow and since the very first call I have never received any feedback as to why the problem remains nor any plan to have the issue sorted. Till date 26/11/20225 I still have no clear answers and I am expected to pay for a service that is not even 50% of what was requested
