Requested contract cancellation, fell on deaf ears and account is still being debited.

Good day

I am writing on behalf of my mother Ms Liza Mashoane, ID: *** who had previously requested that she would love to have her contact cancelled, her request however has since fallen on deaf ears, ADT kept on debiting her account even after she requested that the contract be cancelled hence she started reversing the debit orders because there was no co-operation from ADT. Now recently she received communication from you guys advising that her account is in arrears, can this kindly be the last request that you cancel her contact with ADT, wave all the arrears as she had requested that the contract be cancelled and please liaise with your colleague Dorah who was the contact person, her number is ***. I have CC’d the complainant and her details are below.

Name: Liza Mashoane Contact number: ***
