I am very dissapointed with the customer service the we have been given from Mercury. We haven’t processed a payment through them for about 7 months because we found a simpler, less expensive way to process them…(I won’t say which service because I don’t want people to assume that I am advertising someone else, this is purely a review). We were charged about $37 a month for not using them (which is on us since we didn’t cancel sooner). Then when we called to cancel we were told that we would be charged over $200 to cancel our service if we didn’t send them written notice one month in advance. SO, we sent in written notice and cancelled a month later. In the meantime our monthly service fee for that month went up to $106 and the following month we were charged an “annual service fee” of $222. This was nowhere in our service agreement with them. We called to get reimbursed, were on hold for nearly an hour and then sent to a voicemail which was never returned. RIDICULOUSLY SLIMY!!!!!
