Cancelled but still Debit without permission

Alarm system was installed by chubb security in 2016 agreement was that i pay R356 .. first debit was R615 then second debit was R638 . That was not in my contract at all. Then after the second deduction my husband phoned in to find out why the are deducting so much money came to our shock that we where never on there system . So if my alarm went of or panic they will not recieve it .. so 8i payed chubb for nothing had no protection from them i cancelled the contract and i took my money back .. after sbout 6 months the deducted 1256 from my account i reversed it 4 months later the decuted same amount reversed it agian and block them nov 2017 the deducted agian . With out my permission and without my knowledge .. my contract was cancelled in 2016 so the debit order was cancelled.

Got email from alliance security call centre That i must settle the amount .

I emailed them explaining to them . And on the summons it stated "Ample opportunities have been provided to you to make repayment arrangements. Despite such you have failed, neglected and/or refused to make such arrangements or have failed to make payment, as per arrangements already made" they did not contact me they did emailed me .. so how can chubb say they gave me opportunities to pay and i failed . And i made arrangements ." I made no arrangements with them " lies

And Alliance call centre rep**** sending me a statement and refering i need to settle amount ..

It feels that they did not even take the time to read my statement or my complaint.

How can i Pay Chubb if i got no service from their side i did not even excist on there call centre system .. but i was on there system to debit money from my account.
