Runaround for my refund by Cartrack!!

<p>I have received no joy from Catrack since I renewed my contract with them!! I cancelled existing contract for an old car and opened a new contract but on my second debit I didcovered I was being incorrectly debited (for both old and new contract)!!! Even though I was specific with my intentions. I have now been calling religiously since 6 January (now a full month) trying to get a refund and have been getting nothing but a runaround from accounts!! It is especially infuruiating that cases are assigned to individuals and then only for them not to be available when trying to contact them when calling in!! I have received absolutely no joy and I'm highly disappointed with this service!!!</p>
