This is just pathetic services

When I call the customer service helpline and get an agent who didn't even listen to me giving my account number because she was laughing at a joke her colleague was probably telling and then tells me, \ha ah! The number is wrong""; and I quote;\"" I don't know why you're not understanding what I'm saying.\"" It's not my duty to understand being overcharged when the option was given to me to use debit order! I await a call back from someone who will resolve this issue as soon as possible! Thank you"""
