Discovered something.....

I deposited a sum of money into my discovery account in August. somehow somebody got a hold of my card and began using it online. I recieved no notifications and didn't regularly check my balance. This continued up to date. When I reported the issue to the ***** department, they had a completely complacent attitude towards the amount of money that went missing, and the guy just said that it was verified via a otp so they could do nothing. I destroyed my card 3 weeks ago but I still haven't recieved a new one. It's ridiculous service from the ***** department and from card delivery.
