Ajio — Mismatch of ean number,pickup not done ,money2280 rs not refunded yet.

I ordered size 42 ...and got 44 delivered, also the color and quality varied. I immediately did return the product on app(product I got yesterday evening n then itself I opted for return option)...today the delivery boy wasn't ready to accept it saying that code isn't matching...and then after I insisted he took back the parcel...till now neither the update regarding the parcel has come...this is the worst experience n for the first time m having such unprofessional behavior from ajio. I want my money 2280rs to be refunded back...as in the first place I received the wrong product..and with all the tags attached n bills I returned it the very next day...still m not able to as some code isn't matching which is not my fault...pls check into this maybe the code given is errored.hoping it to get resolved asap.
