IPS Wellness and Health: Deducting money and I DID NOT JOIN!!!!!

I received a phone call about joining as a member. I DID NOT join. The guy said that he will phone the next day. I did not speak to him again. And then I had a debit order for R299 and received an email that said "Congratulations for joining etc."

I emailed them 24/10/19 for the first time and asked for a refund as I DID NOT join. I received an email back. After I've sent 5 emails to IPS nobody phoned me. That is just not right!!!! It is ridiculous. Where did they find my banking details? If I contact my bank to reverse the transaction it is going to cost me banking fees.

IPS = not doing things right.
