Bajaao — Not delivered

I ordered an ukulele on 21st may 2020 on bajaao. My order id is 240083. I placed the order on 18th may 2020 and it was dispatched on 23rd may. Today is 4th june 2020 and the order has not yet delivered. No update on tracking since 25th may 2020.
It was shipped via xpressbees with awb no -[protected].
Courier's customer service no not working and up on calling bajaao customer service, everytime they says a complain has been registered and this will be delivered asap. I don't know what's going on. I feel like i did a great mistake beleiving bajaao to spend such money.
