Wow, -I'm kinda surprised to see that zapit (hosted by GoDaddy, of Tempe, Arizona) was registered in 2001 and from the several background checks I just did, seems to have a good customer relations history.
Zapit is a 'hot wallet' service and I am hoping you didn't have a large sum held there. 'Hot' wallets should be used mainly to onboard/offboard assets but I'm sure you know all this. I did read a few minor reports of 'slow' and 'wait-times' with zapit transaction balances, -which can be unnerving.
I hope this is just a glitch to their part and you get this sorted out...
