Sangeetha Mobiles — Mobile not delivering

Hi team, i have ordered mobile online on 23rd may 2020 @sangeethamobiles.com site. It was supposed to reach on 29th may but we did not get it. Also they are not responding for calls and chats. We went to the store directly they said that mobile is not available hence we are asking for money return. We did not get any response for that. Either we are asking for mobile delivery/money return. Request you to please help us on to resolve this issue.
Thanks,
Pavani
