USELESS service from Supersonic

I am extremely disappointed with the service and billing handling from Supersonic.

A credit was advised as being in progress by the finance team, yet it has still not been app**** to my account after several weeks of follow-ups. In the meantime, incorrect amounts continue to reflect on my statements, and an incorrect amount has already been deducted from my bank account.

The reason a credit is due is because I was billed for a service during a period where it was not correctly provisioned/available on my side. Despite raising this and it being acknowledged through a credit request, the adjustment has still not been processed.

What is even more frustrating is the lack of meaningful support once issues are logged. Logging a ticket seems to have very little effect, as there is no proper response or resolution. In many cases, complaints are only responded to once a week, if at all, which makes it impossible to get issues resolved timeously.

I genuinely wish I had not joined Supersonic based on this experience.

My concerns remain:

• The approved credit has still not been app****. • Incorrect billing continues to reflect on my account. • An incorrect amount was deducted despite the dispute. • The credit justification has already been acknowledged, yet not actioned. • Logging tickets does not result in timely support or resolution. • Complaint responses are extremely slow and inconsistent.

I am requesting that Supersonic urgently:

Apply the outstanding credit to my account. Correct all billing errors. Refund any incorrect deductions. Improve responsiveness and actually resolve logged issues.

This level of service is unacceptable, especially for a new customer, and I expect immediate attention to this matter.
