Won't allow you to cancel out-of-contract debit order!!

On the 20th of April 2023 I sent an email for cancellation and I was called thereafter and asked as to why I was cancelling, I explained that I don't see any value from them, they sometimes come after 5hrs or not come at all when the alarm is triggered and they hardly even call when it is triggered. The lady confirmed it was cancelled but the debit still went off. I reversed the debit but end of May they debited twice, when I asked Absa to reverse they say they can only reverse 1 the other 1 was a debicheck so can't be reversed. Absa told me although a debicheck is supposed to be approved by me, other companies like ADT can load it and approve it themselves, go figure. Absa gave me an ADT number ***) to call in order to cancel the debit order, well I have been calling this number for the past week. Today I used the customer line and they transferred me to cancellation and confirmed the account is still active contrary to being told otherwise in April. When they transfer me my call get cut off, someone call and cancel the call, I call again I am told the system shows someone is going to call me, wait, call again that someone is on lunch they can't give me her direct line because they will walk to her and tell her to call. I call again once I give them my cell phone number the line goes dead.
