Pathetic customer service

I have had the worst experience with Mr Price today when I went in store and decided to buy a product. Then arriving at the till to be told there is no credit on my account. Knowing that I have paid the account every month this was impossible. I am a secondary card holder (and because of this the services reveived was even worse, any secondary card holder should receive the same service as the main card holder regardless). After having a conversation with the counter assistant she tried her best to assist but could not.

The main card holder then phoned in to find out that the card was blocked. How does a big company like this make such a big mistake.

Ps. No reason for blocking the card, just plain incompetance.

Pathetic if you ask me.
