Handling Fee Unpaid

Hi<br> <br> On Tuesday(31st March) i got an sms from my bank notifying me that there was a stop order of R203.50 from Vodacom whilst having sufficient funds in my account. I have been charged R100 unpaid handling fee which i dont really understand what it is about. <br> <br> I called into Vodacom accounts call centre *** and spoke to Vuyo/Vusi(uncertain of the name). He tried putting me through to the relevant person to speak to..after hanging for 18minutes the call dropped. I tried calling in again and this time held for 15minutes.<br> <br> I really need help getting clarity on this urgently.<br> <br> Thank you<br>
