I, had purchased a simple Mobile SIM KIT which costs $0.99 , the counter staff did not know the price and asked me to pay $ 50.00 on my argument that it cannot be so expensive the staff charged me $ 25.00 plus tax . When I, checked with walgreens they told me $10.00 plus tax. due to no knowledge of exact price I, HAD TO PAY an exorbitant price which comes under unfair trade practices, when I approached the store for refund of extra money charged the staff refused to pay me back the extra amount charged by them.
