ADT *******ly deducted an amount from my account, still waiting for refund

I had a problem with the alarm, which ADT fixed. I paid an amount of R 534.75 on 30 April 2020. On 21 May 20220 I contacted ADT following a sms I received re an outstanding payment. I forwarded proof of payment on the same day to Mr Tshikumbana. On 25 May 2020 ADT *******ly deducted the amount from my account. After a number of reminders Mr Tshikumbana inform me that he has been escalated the matter to his manager. So I am still awaiting for my refunds, but has since cancelled my contract with ADT. Thank you ADT for *****ing my money and not finalising my refund. Now ADT wants to know why I cancelled my contract. Really!!!!!
