All Plus Size Store — Credit Card Payments Not Accepted

I know that All the plus size store is closing/cutting down it's business, what i don't understand here is, the stores which are open and open to business, why are they not accepting credit card payments from months together and they accept only cash or UPI, if the brand or the sub brands have such internal issues, they should shut down the business and close the stores with immediate effect, store people cannot/unable to answer this question, they are saying there is no way that i can raise a complaint to Future Group and the All online store website is also closed and there is no way that i can reach the brand and raise this concern, not every customer can afford buying clothes from All the plus size store as the pricing of the garments/clothes are high compared to other brands and hence I use credit card option to make payment and clear the bills whenever I can, request you guys to help & sorry in this issue.
