Muzaffarnagar, Uttar Pradesh, 251001

Dear team

Today i bought a new mobile mi a3 from your reliance store muzaffarnagar at 5:00 pm, but i did not like the phone so i asked him to change it at the same time. But he refused.
I had to change from mi a3 to mi note 7pro
But at the same time he refused to make the selection nor told me whether we will change or not.
Please tell me who will change tomorrow or else i will take legal action

Please check and confirm me on priroty

Regards,
Mohit kumar
