HSBC Bank

Just need to get some help about a transaction I made at a ATM machine. I have already telephone its been over 24 hours and the money has not been put back into my account. I'll give it 24 hours and try and contact the bank again its a lot of money to lose. As it has been taken from my account the ATM closed down or should I say stopped working After my transaction three are cctv camera above the ATM and you can see I didn't get my money. This is a nightmare just trying to get to talk to the right person. I give up I've read everything and done everything I can think of I know see it can take 48 hours. My money should of been returned with in 24 hours so angry I'll be on the phone at 10 o'clock tomorrow just to find out what is going on. So angry and the ai help is a joke it just take you round and round. Sorry I'm just frustrated with it all why did the ATM take my money out of my account it knows the transaction did complete.
