Mweb ineffiency

I have placed an order to move from adsl to fibre. Everything went smoothly until the service provider did not arrive for the installation at 12:30 on Monday 16th November. Repeated frustrating calls to their service call centre has so far not yielded any results. I have travelled quite a distance to be available for the appointment. So far I have not been offered any explanation or new appointment. I have 2 contracts with Mweb and seriously considering cancelling both.
