SAGE ending calls abruptly

I know it is a very busy time of the year with regards to accounting packages, but to call 3 times in a row (if I get assisted (for real) this time) just to be helped is ridiculous. I called the 1st time on ********** 7 between 14:30 and 15:00. I know how it sounds when the call is eventually answered - it was answered and there was nobody on the other side. Later I put the phone down and called again. I called the 2nd time and this time spoke to a (she said) Vanessa, who asked for my customer number - which I have keyed in while waiting. She said that she just wanted to access my profile and probably put me back in the queue as she didn't come back to me. Again I hang up after several minutes listening to music... I am holding now for the 3rd time and honestly trust that my call will be dealt with this time, otherwise I will just have to call a 4th and 5th etc. time, because I can't resolve the issues myself.
