Disappointing service

We are clients of Sage SA, account no LXF0001 we have been paying on invoice for years and all of a sudden an invoice appears on our account and I have been struggling to get the person dealing with our account to correct this, as a result our account has been suspended and we can not assist clients nor can we resolve our own support challenges.

It has costed me a fortune to try and resolve this as all my call are made from a cellphone and yet no resolution has been sucessful, if for some reason my account was in arrears why would I pay 2018/19 license and be issued with a new serial number is the year before was not paid.

I'm very disappointed with the service and we are considering other accounting systems as this would not work us any more.
