Non existent service

My internet has been down since 12 May 2022. Today is 24 June 2022. I can't even count the number of calls I've logged and the amount of times I've spoken to their customer service. Calls get closed without any action and then you need to log a new call and start the process again. Each time I am promised a 24 to 48 hour turnaround time for the issue to be resolved. Given that it is now week 7 this is not an accurate turnaround time. I've tried to escalate it but can never get hold of a manager and my calls are never returned.
