Empty promises and pathetic service!!

We logged ticket number ***4 last week and several phone calls later the matter is still not resolved. During lockdown we are trying to work remotely as far as possible and the internet is of utmost importance. We have been forced to use mobile data for the last week and we all know the cost of mobile data! Yesterday morning, I phoned the umpteenth time, to be promised that the case has been escalated and that I will receive a call back within 10 minutes. At the typing of this complaint, 170 ten minutes have passed,
