Regarding the cheating I faced from an Instagram store

I ordered a package on 13th March ,2022 from @clerby store from instagram.I received my order on 18th for which I did my payment.but after opening the order I found that I received the wrong order.For which I texted them via email .Their email is clerby.store[@]gmail.com
They replied me saying I would get my right order or refund within few days ..It’s been nearly 3 weeks but I still got no reply from them..please help me get my refund..
I’m a student..so money is really tight and important for me..please help me.
