Vox Telecom bad service

Our Company Ahead office furniture signed up with Vox Telkom. The first sign of bad service was when we were billed from the date that the techinan connected the service and not from the date we went live with the PABX. We were sold a ten port switch which in actual fact is a eight port of which Vox use two of the eight switch's. So effectively we only have a six port switch. We are unable to connect our other devices due to this. Vox undertook to sort this out. Emails that are sent to the Vox sales rep are read, but nothing further. Do not use this company.
