Disconecting my dstv on paid acc

In December multichoice have cancel my debit order because I upgraded to the premium pagage. Since then I only had problems with them. I spent more time on the phone to fix the problems than I spent watching t v . End of January they disconnected me for not paying my acc. My acc has been paid on time. End of February they disconnected me again for not paying my acc. I have phoned them on Friday 6 march 2015 to be reconnected and mailed them the proof of payment. On Monday 9 march 2015 the send my n sms again they are disconnecting me. So I mailed the proof again. <br> They have even promise me a free box office movie if I pay before 07mache 2015. Results are no movie no dstv and my acc has been paid <br>
