Multichoice refuses to refund my money thats in advance - custnr ***

For years now my son pays into my MultiChoice account for my birthday/Xmas and presently I am R2 700 in advance. I am now forced to cancel my subscription and requested the refund. I was informed that they will not refund me but my son. Then i had to get proof of payments from my son of more than 1 year ago, his bank statement AND copy of his ID !! After 12 emails of getting requests for different documentation I am of the opinion the do NOT want to refund and keep sending me in circle via emails - Now looking forward to cancelling my subscription.
