What the hell did WISH do?

I purchased something on wish and my payment method is Paypal. I had the required amount and they deducted the amount from my paypal. Today I get a sms saying wish has debited my private bank account. When I checked my paypal to see what is going on, I saw they credited me the $ and debited my bank account. Outrageous and pathetic. I need this money credited back into my bank account.
