Brand Factory — Closed without prior notice

Hi I am Wahab khan.I have purchased some clothes from brand factory kolkata which I exchanged later and too a credit note on behalf of it.Its been 4 days I have been visiting 2 to 3 stores of brand factory in kolkata but all are close and no information about it.Finaly I met a security guard and he said that it's been taken over by another company.I called the customer care executives but they did not provide me a proper response or solution.I am afraid my money will be wasted.Please help me regarding this matter.I still have my credit note with me.
