Does anyone has any idea about ZeeSpares?

Hi, I ordered my pixel 4a front glass from ZeeSpares and accidentally ordered the 5g variant. It was delivered to me on 5th of January. I wanted to return it. And they sent me an email that they'll process my request. Didn't got any reply so I thought of calling them and asking them about yhe progress they told me since it was my mistake so I'll have to courier the product to them. Should I do it? Although the product I received seemed good in terms of quality!
