Horrible Service

To say I'm flabbergasted its an understatement, I requested for my banking details to be updated 2 months back, guess what only one policy was updated and the rest was not, why I don't know, and if that is also possible I don't know, I then requested to cancel the whole policy yet they kept debiting my account for what ****en reason I don't know now I have to pay errors that I didn't even plan, please refund me and pay for errors you made with my old bank
