Hi there and welcome
Can you remove the battery please then hold the shutter button down for 60 seconds then release.
Wait 5 minutes, put the battery back in and try to turn it on.
Tell me please if it now functions correctly
Can you put in a different memory card into the camera please and tell me if with this it allows you to take a photo .
I called but it says it is not accepting calls and to hang out? Maybe you have a block on private numbers?
have you tried a different memory card?
