Respected sir/madam,
I bought a mobile on 4.10.22 of OPPO A76. I asked to the sales person it's a 5g model they mentioned A75 aspect of same of version. A76 is a 5g model. The main thing for bought a phone of 5g only. But I check the phone details in my About phone it's mentioned as 4g mobile. The sale person cheated me and give a 4g mobile. She told me when I called to her we can update at the time. there were option will be reflected at the time.
I checked through internet OPPO A76 is a 5g model.
Kindly change the mobile of 4g to 5g model. I asked to the store once we open we cannot exchange it. I humbly request you to kindly solve my quarries and allot me a 5g mobile.
