Bad service for Cell C Fibre

I previously asked for my month-to-month on the to be canceled due to your poor service delivery after I asked for a new contract because my router overheated. This took 4 days and nobody ever logged that I'm willing to do a new contract. Neo called me on Monday to try to remedy the problem. Arranged a reduced premium and said my installation would be expedited. it is now day 4. I asked for it to be canceled again. However, I'm not receiving any feedback! I urgently need assistance as its now more than a week since I started this
