Debited 3 times

U guys have debited me after I have made a payment to u for the full amount, I have sent through ur proof of payment, yet 3 days later I get debited, and then u debit me for the second time 2 days later. Like what the ****.... And to get my money back will result in some mess up next month as I've been through that scenario before. If it's not ur sales agents calling every single day then u mess up my credit rating. I want my debit orders to be cancelled as I will then start paying u manually cause God knows u people like to **** up everything.
