Ample Technologies — misleading product being sold by imagine (apple reseller)

I have purchased a macbook laptop from imagine apple resellers website.
The description mentioned that the laptop’s processor is i5 10gen 2020 model. Whereas the partcode number which i have received in my email is (Mwtj2hn/a) which is i3 processor.

My order id is r[protected]
Date of order is 14july 2020
I want to raise this complaint as this is a serious concern. And i wish to cancel my order and get refund immediately
