Negative Rating

Please advise how I can give Supersonic a negative rating. This is the worst service provider in my opinion.

I have not been invoice or billed since starting with this service provider on 27 July 2021. To date I have called Supersonic begging them to send me up to date invoices so I can claim from my company since I am working from home. My company will not accept any invoice older than three months.

I was told by a consultant once they see what the problem is they will send my an invoice. This invoice will be for five months. Three of those I will not be able to claim for.
