Being billed for not excisting policy

I wonder if Sanlam will gett it right this time???? After billing me for policies I DO NOT HAVE, AND AFTER CANCELLING IT NUMEROUS TIMES, once again I was billed for these policies in April and May! The last time I contacted Sanlam about this policies I am paying for was in March, so after cancelling everything they just went and deducted everything again the next month!!!! After once again assuring me that everything was cancelled AND that all my details were removed from their system!!! This is not acceptable, and the worst is they will contact me today, apologize, refund the money wrongfully deducted and then the next month the same will be done again all over again!!!!
