Incorrect debit order date

I have been with dot sure for years without hassle, until my debit order goes off on the 24th when i only get paid on the 25th, was told by the consultant that this was because of the public holiday. I asked to cancel my policy, consultant called back 5 mins later to cancel, goes to show that dot sure does not value thier clients, did not even try to assist, or even escalate the call to a manager. Very dissatisfied
