Arrogant , dishonest Fidelity ADT

I informed ADT that I want to cancel my contract with them in February 2023 and a Xoliswa Khumalo called and offered to reduce the subscription which I agreed to even though it was still expensive than the alternative simply because I hate the changing admin. By end of February, ADT deducted the old amount and I wrote to them alerting them of the earlier agreement and again Xoliswa Khumalo called and apologised saying I won't be billed for April - I asked for that in writing abd I never got the email. End of March, again full amount was deducted from my account. I sent an email again asking for termination by 30 April. On 13 April I got an sms that the account has been cancelled. On 30 April I was charged again yhe full amount and when I called today I was told some agent scheduled the cancellation for June. I was put on hold to speak to the agent who scheduled the termination until I got disconnected. This is very ********* of ADT and its employees - seemingly once you sign with them, it's for life. Please think twice before signing with ADT - they are too big to care. Even the 1 star rating is too generous.
