Cannot convert BETH back to ETH on Binance, please help me

Hello everyone,

I've been staking ETH on binance for a little more than a year and half and it was converted to BETH during that time.

This week I decide to unstake it as I wanted to have it available in my spot wallet if I wanted to sell ETH.

When I went into the ETH Staking section on Binance it asked me if I wanted to convert BETH to WBETH which I was not interested into as I just wanted my BETH back and convert it to ETH.

I redeemed my BETH and since then I have been unable to convert them.

Seems like it was obligatory to convert them to WBETH first so I could convert them to ETH on Binance platform which wasn't advertise nowhere in the message I received.

Now I'm stuck with useless BETH that I can't sell and can't convert back to ETH.

What can I do to convert my BETH to ETH please ?

Thank you
