Aurelia — kurta exchange or return

I ordered a kurti from shopforaurelia.com on 4/09/19 but the size is bigger than expected i. E. I ordered xxl but have realised that xl would be perfect.
I want it exchanged for a smaller size or returned.. Whichever possible.
The customer care number can't be reached and i am unable to locate return option on the website.
Please resolve the matter soon...
