Zivame — out of 6 items listed but 3 items not delivered

I had ordered few items from zivame on may 24th 2020, i got the package on 11th june 2020. I have already sent 3 emails and in my first email i had sent along with screen shots of the items that i have received but there is no response. There is a customer care number which does not work. Every time you call it would say we are closed for the day please send us email. And then u keep sending emails. I want refund of the items which haven’t received or resend my items which was not sent earlier. These people’s site also never work to give any query.

The order number is 79450451.
