Pathetic Service & Support from Sage South Africa

We recently signed up to Sage Business Cloud, what a joke! The knowledge of their support staff is absolutely pathetic! I own a small business that imports good from China amongst other countries and sells them locally in SA. We purchased Sage's Multicurrency module thinking that would cater for our needs, only to be told (erroneously I suspect) that one cannot input cost of sales from foreign suppliers in USD and then have your sell price in ZAR without changing your home currency? We buy goods in local as well as foreign currency so this is just not feasible, and my accounting need to be done in ZAR. I think the software is probably capable of this, however the support staff clearly don't know their product and and keep saying they will revert back to me. Only to get some vague answer that does not solve the problem. Furthermore after hanging on over 30mins for their retention dept I'm still trying to cancel our subscription. Very disappointed in Sage South Africa!!!
