2 months and still waiting

<p>I have my own business and use Nedbank merchant for my POS. They have been over charging me going on three months now and not doing anything about it. My personal banker has even tried to help me but their merchant department is useless. On the 20th of September I asked them the first time why they are over charging me and look at the date now. They tell me they will call me and I have not received one phone call from the merchant department. This is not my first time having appauling service from Nedbank merchants. </p>
