Ajio — Issue in returning one order

Its been more than 10 days since I’m trying to return one order .
The order i have received is wrong . I ordered size s and got size M now from last 4 days i have been trying to call customer care and i was told order would be returned by 8 of January but still didn’t get any call from ajio . In app its showing returned attempt was made my delivery partner but in reality there’s isn’t any attempt made . So please solve this issue asap now its getting on my nerves.
