Adt debits me in error and totally ignores me for weeks

On the 4th of January 2021 ADT Debitted my account in error. Today is the 21st and despite me sending proof of the debit order going of my account ADT has not refunded me.

I've been dealing with Nthabiseng and Lennox whom never ever bother to get back to me and I have to keep following up with them.

Adt has sat with this money for weeks and are still going to debit me this month, which is unacceptable,

What is most appalling is their lack of customer service and just the basic of giving a client feedback.

I've even copied some of their seniors, Kelvin and Marise whom also dont respond.

This is pathetic service and I wish to terminate my subscription with Adt and you better not debit me come the 25th January
