Bad Customer Service

Was so disappointed. Bought clothes using my account but was told my signature differs from the one at the back of my card. Which is true as my card is kinda worn out. However, I am not happy with the treatment I got, as I was made to feel like I am a *********. Waited for over 20 minutes for them to verify my account despite the fact that I had my ID with. The sad part is, after the call center confirmed that indeed I am the owner, still, I left with my card as is, as No remedy was given to me to avoid this in the future. So, does this mean each and everytime I buy from Ackermans, I need to spare 30 minutes just for them to perform security checks??? Ridiculous service I tell you, Moreover if you are a loyal Ackermans account Holder. Very disappointed. I am even considering closing my account.
