SamiAhmed, please do not accuse The Levitate Team of lying, as we are not.
Our Discord login on the exchange Discord channel was and still is banned by the exchange itself.
We were bluntly cut off from communication and kicked out of their developers channel.
So don't come up here saying we did or do not contact them.

What apparently caused the problem was the exchange installing the new wallet but forgetting to direct it to a new data directory and different port while they still had the old wallet running too.
It caused the old wallet to crash and the new wallet not to work. Then they restored the old wallet temporarily so people could withdraw, and then they closed the old one and did not yet install the new one.
There were and there are no issues with the LVT wallets.
