Supersonic poor service, no contact, over charging on invoices

Whoever is considering purchasing supersonic. I will warn you that they are very difficult to get hold of and you can test their Whatsapp it does not work. They also invoiced me 4x my invoice amount and I cannot get hold of them and they disconnected my subscription and I can't resolve the problem. So we filed a ******** case against them and will be posting the progress of the case on all their social media accounts.
