Frustrated customer

i honestly don't know what to do because multi- choice they are giving me a problem this is the second complaint about them. In February i paid my monthly subscription and my Dstv was disconnected because they said they couldn't find payment i them proof of payment more than three times and my dstv was disconnected more than four times and today when i went to pay for March they said to me i never paid for January knowing the is a possibility that i wont find the receipt for January , and when i called them nobody ever mentioned January payment they only mentioned that they couldn't find payment for February. Im so frustrated now
