I'm entitled to a refund amount and interest. It was processed during 6 months, not 45 days.
A reason I returned, is cos I claimed payment I made after 15 of Jan, and it was part of the return, but they also included it on top of the refund. So in fact I received this payment twice but was supposed to have just once.
So I'm not entitled just for part of the check they sent. I can't take just interest and return the check.
I hope it answers your questions to help clarify the case.
