Incorrect Billing

I enquired over the phone to upgrade to the Explorer package which I then approved, the guy from multichoice told me it will be delivered within 48 hours and that when I have installed it I must phone them. 48 hours went by and the explorer was only delivered a week later when I was already on holiday. I came back 2 days ago so haven't had time to install the new machine can only do that next week. <br> <br> now multichoice has billed me pro rate from the date the machine should have been delivered that wasn't and also for my other decoder. so now I am paying for a service that I was not using in the first place. And also paying for both decoders, how is this possible. the Contact centre people cant assist me as they don't know what is going on and told me to phone a different number which I did with no answer what so ever!!!<br> <br> This is un acceptable and I need my money back that they overcharged me. Bad bad service from Multichoice. Never ever make use of their deals over the phone rather just buy the explorer than tryng out their new deals!!!
