Handed over due to Bank error for R44!!!!!

I closed my accounts with Standard Bank 6 months ago. <br> 2 months after that they contacted me about a balance on my garage card facility. <br> I contacted them and they indicated that it was a service fee they charged after my accounts had been closed with them. <br> I was informed that they would reverse the charge and that the matter was closed. <br> Today I was called by an attorney as they handed the matter over for collection - for R44-00!!! <br> This is unacceptable as I was assured that everything was in order. <br> If this results in adverse entries on my credit records, there will be fireworks. <br>
