Poor Service. Poor Accounts. Poor Conversation. Poor Multichoice

I reactivated my services with DSTV about 2 weeks ago. I started on the Compact package and paid about R 250 to cover me till the end of the month. I now wanted to make a payment for the new month and saw a balance of R 1000, very shocking. I called into the call centre and spoke to Shandre, and she told me I have 2 decoders on 2 packages. I have no idea how this is possible as I only have the 1. The consultant named Shandre, refused to assist and kept saying I have the 2 and I have to pay for the 2. Where does Multichoice get all this from ? I will never pay this amount due for goods I do not have and never have had. This needs to be sorted out immediately, cant believe I reactivated my services only to see this. The service I received from Shandre was appauling, there was no desire to assist or look into the matter
