Still not able to resolve Customer Issues.

I complained last week about Metrofibre's inability to resolve Customer complaints. They sent a Technician on Sunday morning, who gave me yet another temporary solution similar to what his Colleagues did the previous weeks. It's Thursday, 4 days later, we siting with the same problem. We don't have internet. This is the 3rd week in a row. The pattern is that I will report the fault, they will dispatch a Technician on Saturday or Sunday, who will switch me on for a day or two and then we won't have internet. The when is this going to be given the attention it deserves
