Very unhappy with the poor to no service from Sage - Paying a huge fee for a product that does not work properly.

I have been trying for well over a year now to get our Payroll package to work properly. Last year in the beginning of the new financial year Sage managed to sell me on upgrading to Sage 200C - this package was so full of flaws I don't know why they released it. Even the consultant who came to see me could not get all the functions to work properly - we paid her for the service to come and install and train. By the beginning of this financial year I was so fed up I told her I wanted my old payroll package back - they put me back onto Sage VIP Premier. Ever since then the payroll system has numerous issues. No one will assist me with sorting it out - all because I refuse to pay for them to get it to work properly - I feel I have paid enough already and I just want a package that works - I don't see why I have to sit and manually calculate leave because the package calculates over four days annual leave in a two week pay cycle. - that is only one of my issues. Now I have recently found out that they have blocked my account because I refuse to pay for them reverting me back to the old payroll package. Anna from accounts promised she will get it sorted and get back to me - that is now almost five weeks ago and I have spent quite a few hours holding on the line listening to various messages over and over trying to get hold of her - to no avail! I had Tamzyn promise she will get her team to assist me with all my issues at no cost - but now she has left and only one issue was sorted before that.
