Zero communication for a communication company

We have been trying for almost a month now to organise fibre at a place we moved in to 1 September. We are in a contract with C-fibre, and the new place has fibre in the complex, just needed to get it into the unit. We tried to arrange that for the day before we moved in, but after various attempts to organise it, the eventual communication was that it would take 3 days to a week to get a technician out. No need to say it was rather the latter. After installation on Friday 8 Sep, we let them know on Saturday that something is not right (we concluded from the info pamflet they gave us). We provided all our details, initial order number, object number, etc. It took them 5 days to eventually send someone out, only to let them pitch up FOUR times at our previous address. After the third time, my husband spent half an hour on the phone with Vumatel office, to try get the guys on track. The lady took the address and apologised, promising the techs will still come out tonight. An hour later (3 hours after our appointment with them) the previous address gate calls me. Three times, trying to have a conversation over the intercom. ***? How can you go the wrong address AGAIN? And how does your technicians not have cellphones to call the clients they need to see? I can not believe the terrible service. And the fact that they are a sole provider in a big are of Joburg, makes it so easy to have a '***** you' attitude. Very disgusted, disappointed and angry.
