PATHETIC SERVICE CAN'T CANCEL MY CONTRACT

Can I please get someone to assist ME with cancelling my contract with Vodacom.. I called the call centre yesterday and spoke to Portia and advised that my account isnin areas but my contact ended in June.. so I was transferred to a different department. I wasn't sure what department was that den the lady I spoke to she dropped the call gr8 service I can say. I called again to ask to speak to a Supervisor and I was put on hold for 10 minutes with no response just music playing in my ear.

I JUST TO CANCEL MY CONTRACT IS THAT SOOO DIFFICULT TO DO.
