Intant withdrawal taking 4 days

I made a instant withdrawal on Friday morning and it was declined by the bank , called hollywoodbets and they said the bank must of been offline and it will be reversed into my account within 24 to 48 hours. Waited the period and still nothing, called them again and I was said I have to wait another 24 to 48 hours. Why must I wait over 4 days for a instant withdrawal. Hollywoodbets I need my money
