Horrifying Service

I ordered a fibre line 2 weeks ago, someone came out to do the installation but due to technical issue he could not and had to return to Mweb with the feedback. Since then I have not heard a single thing from Mweb and when you call them they ask you to leave your number and they will call you back. I have left my number around 9 times by now and have not heard a thing. I received a single SMS where they said OpenServe has issues and that I should not call them, they will let me know. This type of service is absolutly horrifying. I have no clue when to expect anything and I have no one to call to escalate. If this service starts out so horrifically. I do not want to know what is install for the future.
