Do not want any dealings with your company

It's quite distressing and disheartening that I have to cancel Tracker. I mean, I informed you the dates on which you should debit me. You chose to go to my account on dates that we never agreed on, days before the agreed-upon date. Taking money that was supposed to last me a few days before I got paid, causing a significant financial disturbance in my life. Not only that, but you took a sum that was never agreed upon, with no explanations or even a phone call to explain. I cannot cope with a dishonest company. I've stopped the debit orders. I want nothing to do with your company.
