Yepme — ~8K orders not replaced/refunded for a month now

I placed two orders with Yepme on 24th July. Their size chart was completely off so all the clothes ended by being too big, so after getting the appropriate RMAs, I shipped it back to them. One order was supposed to be replaced and the other to be refunded (their ridiculous software won't allow items with an order to be selectively replaced or refunded!). They notified me of the receipt of the return and I was told I will receive the replacement order and refund within 7-10 days. It's been a month now and every time I ask for an update the only response is "forwarded your concern" but with absolutely no reply from whomever these concerns have been 'forwarded' to. When I asked their Facebook staff for the matter to escalated, they blocked me. This is Yepme's method of 'resolution' apparently. If Yepme does not resolve this in the next two days, I will be filling a dispute with my bank and insist that they impose a chargeback fee on them when they recover my funds. I've tweeted the cofounder Sandeep Sharma (@sandyxyz), brand ambassadors Rhea Chakraborty (@Tweet2Rhea) and Esha Gupta (@eshagupta2811) about this reprehensible and shocking lack of customer service, bordering on fraudulent activity. I think they believe if they wait long enough, we will forget that the refund is due! I've also re-emailed Yepme and forwarded them to [protected]@yepme.com, Lalit Kumar ([protected]@gmail.com) --provided by another complainant. I will definitely be taking this forward with consumer court as well for not only my funds but for the waste of my time and resources. Online shopping is supposed to make life convenient, not waste endless time and phone minutes to barely get a non-answer, contact the company owners and file complaints/court cases.
