Poor service and ill-treatment by John Craig

The staff from John Craig are unprofessional and pathetic to say the least. I laid a complaint over the store failure to update credit bureau information and they dismally failed to solve the problem after sending me from pillar to post within their Call Centre. I then decided to settle the account and closed it and after paying it in full the store saleslady called Head Office to ask for the letter acknowledging a closed account, firstly the Head Office hung up on me when I tried to explain why I wanted it closed. After calling again, the person I spoke to told me they cannot issue me a note to say that the account is closed. They said I should 3 to 5 working days for that note. Why should I believe them whereas they failed me more than once? I regret having an account with them.
