Vumatel disappointment

Disgusting service.. Previous occupants of the house we moved into had Vumatel fibre, so it seemed the obvious way to go. I apply for fibre. On the 26th May I get an email saying it has been activated.....hmmmm - no internet. This is finally up and running on the 6 June 22. I'm not sure how many emails were sent back and forth - most emails I received had the phrase "escalated' in them. I have been billed for this service from the 26 May, when I questioned if a credit was going to be passed for the period 26 May to 6 June 2022 I was told they wont do this as it was a technical problem!!
