Reaping of clients money, accountability and unprofessionalism

Vodacom has started again with unprofessionalism and reaping of customers. I cancelled the insurance on 01/10/2018 however on the same date I was charged R20 extra on my premiums and then this month 01/11/2018 they still charge the full insurance. May I please have these funds reversed I want my money I'm tired of you Vodacom not making sense for taking my money , I want it. I called through on 02/11 I was sent from pillar to post to 4 different consultants, cancellations, insurance, customer care & accounts division but no one told me exactly what to do , only the last one who sent the statement's for last 2 months but what to do after, I don't know and they don't know too. Every time I get the worst level of incompetence. The no in question is ********** 210. Reverse R20 from last month and R149 for this month and next month I don't want any problems my premiums should be R508.00 not more, can I just get my money back and be reliable and honest to your client's without being out of context for once.
