treat your customers fairly!

I asked Tracker to change my debit order date from the 25th to the 20th and somehow the incorrect account number was being debited - how does this happen when it was just the date. I had to pay late fees for amounts not collected. In Jan after calling into their call center and confirming my account number for the debit order again, and receiving the email confirmation it is still not done. I received an SMS stating that they handed me over to a collections agency without once calling me or checking their system. Why as a client must I keep trying to correct your issues. Please rather cancel my contract and take your system out if you cannot provide customer service or treat your customers fairly!
