Bad Service from Sage Payroll

Every month when we have to run payroll, we are told about outstanding invoices 335471, 324877, 345127 and 354231. They were paid a long time ago and we sent Proof of payment. They would open and the following month we would go through the same process. we tried again today and it was open but as soon as we attempted to roll over to the new financial year we encountered the same problem. We tried to get assistance the whole day and after being sent from one number to the next, most of which were not answered, I was kept holding until 16:00 when the system told me I reached the number outside working hours and cut me off. I'm sure everybody at Sage has been paid and they can spent the weekend with their families while our employees cannot be paid. The treatment meted out to small companies is rotten.
