Not respecting clients rights, and taking advantage of clients

AUCTION NATION is ripping clients. I explain why I say this. On the last increment, auction Nation is supposed to mark an item as sold. Instead, when it is the last increment, which is R250 on their side, they will recount the same bid for even 4 or 5 times, so that they can tempt other people to add their bids, instead of giving the chance of the person that won when the count reached Zero (0). I have got screenshot videos to support my saying. That, in many cases, make prices go even higher. Another issue is of the refundable deposit. You pay the refundable deposit, and their terms and conditions state that you can get your deposit within 7 working days. However, you get an email from Workers or fiancé staring that you will get your money back 14 working days from the day of application. That goes in direct opposition with their own terms and conditions. I would like to know what need to be done in this situation I think the solution will come when clients unite and bring them to court, with supportive proofs that we hold.
