bad service

I made a payment on my multi choice subscription on the 22nd of Dec since I was worried that the 25th will be a holiday and they might not debit me in time. Now on the 23 I realized that this money was paid into a wrong account being my mom's subscription with Multichoice, I then called their contact centre and forwarded the proof of payment for the funds to be allocated to the right account. To my surprise when I woke up these morning my subscription was suspended. I bought up to 200rands airtime trying to fix this with consultants, sending emails with the proof also asking feedback but nothing happened I just had to do the same thing all over again and buy more airtime. Even sent proof of notification directly from my bank, they still can't receive that as well. Should I buy another 100r airtime and go through the same steps with them. Why should I waste so much money o airtime. Why can't anyone respond to my emails. Is it fair that I'm spending my next payment money for subscription on airtime. Every time I call I must still follow the same steps. I'm ****ed
