Worst Service provider ever Supersonic

Full payment taken by debit order... A few days later my internet is off. Nobody can tell me why it's off or who gave them the authorization to cancel my line. I was told they escalated the problem to the project manager and no feedback was given. Everytime we call they repeat themselves "it's been escalated to the project manager". 72 hours has passed nothing has been done. What's the point of having customer service when they cannot help you... There job basically is to escalate to the problem to the project manager who also take there own time. I won't recommend supersonic fibre. They do not do what they suppose to do... To many problems.
