NEDBANK POCKET POS AND SERVICE

I opened my small business account during 2014 at Nedbank Savannah - there the service was wonderful. I ordered a Pocketpos for my business - received that very quickly. Since I got the pocketpos last year October, I only could do one sucessful transaction due to the pocketpos never having reception, although my phone has full reception. I then requested Nedbank to cancell the pocketpos - it's now been two months and still not have the money back in my account, after numerous calls and emails. Now, in December 2014 there was R526 deducted from my business account. Again i phoned Nedbank to enquire about the money, what was it for? Then i noticed that pocketpos charged me twice for the administration fee!! Nedbank then came back to me after weeks and said I have a diners club account, which I never had in my life. Then it was a transaction on the pocketpos, but if it was a transaction, my account would have been credited and not debited. It
