Bad Service and empty promises

Mi Way have difficulty of cancelling my policy firstly it took 2 emails and a query on their website after 2 weeks for them to decide to phone me back. and then they never cancelled my policy like they were suppose to because their cancel button didn't work really!!! and then they took a full amount of the policy debit order off my account and I'm still waiting for my refund as there is a problem again with their system. They always promise to call back which they never do! I must always phone them and hold on for so long just to get another excuse and nothing have been resolved yet again, that is why I cancelled my policy in the first place because of their bad service
