FNB MERCHANT SERVICES HAS NO SERVICE

I have been an FNB BUSINESS CLIENT for longer than 2 Years. My Speedpoint is with them as well, my Speedpoint was costing me R240 per month Ex Vat and all of a sudden my December statement this has doubled to R480 exc Vat and when I call I get told oh I was on a promotion!! A promotion for longer than 2 years and now my rate doubles? Is this how FNB MERCHANT keeps there loyal clients satisfied? Maybe not call yourselves your a Merchant Services if you can't provide Service..
