Refusing to accept my cancellation and continuing to debit my account.

I would give 0 stars if I could. Long story short: replaced battery without quoting first or me authorising the work. Tried to arrange payment plan, but they simply increased the debit order to include this unauthorised invoice. Is that even legal? Canceled my contract with Blue via phone, e-mail AND their online form and still no response. Another month, another debit order. Being sent from pillar to post. Pathetic service. Phoned again today, and there is "no record of my cancellation". Sorry to name you, Cathy, but you were very happy to sign me up and you have not assisted in any way.
