Monies not over

We own 3 holiday homes in Margate.So we got a credit machine from a Sureswipe 3 months ago to charge our guest .All our bookings are done through bookings.com . We have charged 3guest through the card machine on 18October 2017, which were successful for Total amount of R23350, to date Mercantile has our money .they have not paid this over to us .

Even after Sureswipe Regional Manager Daniel Baney had visited us , and has seen and collected the confirmed bookings and the successful transactions information for these three payments . Four weeks have gone , why has Mercantile bank not paid us. Why has no one from Mercantile contacted us. This is our money. The bank has no right to hold this money.
