Please refund me the initiation fee that you deducted.

A couple of months ago I wanted to do a brand switch from dial direct to budget, well after a lot of things were required from me I decided not to carry on with the switch as when I switched from ffw it was much smoother and now it proved to be a tedious process. Meanwhile some fee was deducted from my account and no one has even attempted on refunding me this amount. Plz may I have it paid back asap with interest as it has been sitting in your account since.
