7 weeks- stollen refund!!

It has been 7 weeks since I returned a cologne and I still have not been refunded. Stuttafords incorrectly reversed the charge on my debit card rather than giving me cash- they admitted fault for this. I have been in contact with head office and repeatedly nothing is being done. They have contacted the bank to no avail. I have sent bank statements and called my bank at the request of Stuttafords - all times my bank has confirmed the money is not in my account. Further, Stuttafords has made no effort to contact me.I have to chase after them. I called a week ago upon still hearing nothing since my last call and am still waiting for a call back informing me of any changes. I am really frustrated nand unhappy. The staff keep apologising, however, this does not fix a solution or help me.
