They are refusing to pay back my money

Good Day

On this day 06-07-2017 i bought two jackets online , on this Dressinn shop with a visa logo . unfortunately they fail to delivery . this year around April they decided to refund me to the account that was use to buy those items.

The problem is that very same bank(FNB) account i use to buy those items was close earlier this year.

i then request the shop to refund me to a different accont, of which they refuse to do so , they told me the money is now with the bank.

i then went to the bank(FNB) for almost the whole two months demanding my money . the bank told me they cannot help me since the account is now closed and shop says the money is with the bank . At this point who must i contant to get my money back.

i will welcome any assistance or any direction from here

Thank you
