POOR SERVICES

I am disappointing in Milady's. I've been a customer for years. I know the quality is not that good as before, but I love their clothes. The reason for my review, I paid up my account, and October 2020, I received my Statement, and on that Statement was a SIM TOP UP for December 2017. I was in New Zealand that time. They sent me from one person to another person, they cannot assist me, or even tell me what it was, and I wonder how many times did I pay for that SIM, that I didn't saw on my account. Why is it so impossible to get service??
