I received a call from someone asking me if I would like to change my debit date for December and I advised no, I want debit to go through as normal at the end of the month. They took it upon themselves to debit me on the 24/12/2024 causing financial difficulties for as it was the day before Christmas and I now had to borrow money for transport to go to work for the days I'm due to go to work. Their number doesn't give you an option to speak to someone, I sent them an email on the same day, asking for my money back as I need it but I haven't received any response from them. Instead, they sent me a message thanking me for the payment. The same payment I did not authorize for the to take.
