Ajio — Received totally different item then what was ordered

Order I'd : FN[protected] and Return I'd : RT[protected].
So I ordered the pink self striped round neck top from brand rio, a very well known brand of Ajio and got the thing which is not even a top it's a shirt and it is totally different from what I have ordered. And the funny thing is that the tag is from the same top that I have ordered but the product is different. Because I searched for the product I have received, the different one, in the website it clearly mentioned that the product cost 699 and this thing which I received according to the tag it is 799. How is this possible? When I tried to call the customer care, I only had to listen to a few system generated words. Then I connected through chat and luckily my return was raised. Please look into this matter. I have been shopping from Ajio for the past 2 years but have not experienced this kind of issue.
