ANGRY AND FRUSTRATED CUSTOMER

I have spent over R200 on my cellphone calling multichoice. I have called them more than 5 times spending over 30mins at a time where they double billed me and now disconnected my services. They acknowledged to have made a mistake but not rectifying it since 2 weeks ago. I since sent them proof of payment but have not gotten any joy and its sooo frustrating. I have been a member for 10years now and I am so distraught and have had it with MultiChoice. It's ****************!!
