Bad service

I had canceled my insurance with FFW and I remained with my tracker. Altech tried debiting money on the wrong dates which has left my account in arrears. I tried calling to change the debit order date, yet their customer service number on the website is incorrect. I tried emailing to get someone to call me but no response. I received an sms telling me that they will debit my account on the 15th which again is not the correct date as I get paid after the 15th of every month. I'm not happy with the service at all. You guys will be attempting to debit my account on the 15th again which will cause my account to be in arrears again. I've never had any issues with you guys before until now. You better make sure some calls me as soon as possible and change that debit order date or replace my bank charges!!!!
