Tracker thinks there customers are very stupid!!!!

So tracker thinks I am to stupid to understand the reason my account number was changed, yet I am the one who informed them of the problem in the first place. They debit my bank account without informing me (not the first time) and in the meantime I go to the bank to make payments on my old account. The complaints department couldn't be bothered if I tell them I will go to another company.<br> <br> I have so many complaints about tracker since June/July 2014. They couldn't to give me feedback yet I contact them almost every month. They ignore calls, e-mails and every time I have to explain my story to a new person.<br> <br> Cant supply me account number they may have changed it again!!!!
