Poor customer service

Initial amount swiped on my card was less than the tag amount. Then I was told it was short and I would have to pay more. I was fine with a second card swipe however I was then asked for more than the tag price. At which time I got frustrated. Comment from the lady assisting was 'I am trying to sort this out', accompanied with a sigh. No apology from the sales assistant or manager(s) on the floor for the 10 minute transaction. I requested a cancellation of the transaction to be told it would be 10 days with some paperwork to fill out. Have been a loyal customer, I will not be back.
