Terrible service with Snobbish Call centre agents

I’ve had such a bad experience recently tell me why this people sent me a sms to tell me they had technical difficulties hence my direct debit wasn’t taken and that if paid I should get ignore or they would take another on the next working day . I then made a deposit directly to them tell me why was there and extra 2 direct debits then taken thereafter literally all my money out of my account I call the contact centre the snobby agent I spoke to tells me there’s nothing she can do as it’s not reflecting on her side that they have taken an extra 2 direct debits bare in mind I called them a whole 24hours later so how can you tell me it’s not showing I ask her how do I get my money back and she tells me I need to call round 12pm to the financial team cause only they can advise so right now finchoice is sitting with 3 payments that was taken from my account and I still have no idea how I’ll get my money back . I appreciate the service I’ve had previously but what happened now was just the last straw .
