Incommpetent salea lady

Bought globes for my daughters car,quite expensive. When I got home we had a discusion and she decided she could not afford. Went back next morning to Midas. Product was un-oppened and in tact. Lady said I have to pay handling fee wich I agreed to. At the till I saw amount was high and I asked sales lady how much handling fee she charghed,25% she said. Went home unhappy and phoned a couple of Midas's and they said either 0% or 10 % .I then saw on the slip at the bottem it says 15 % . Phoned East lynne Midas and another sales person answered I asjed him about handling fee wich he also said 15 % .I was put through to the sales lady and conftonted her she said she usualy askes 20 or 25 % depending on how much customer spends. But I can come in to solve the problem. Had to go back and after a debate I got all my money back. Because I told her she was *****ing from me and how can she ask 25 % and policy says 15 % . Her reply was that she doesnt get customers who returns stuff. Her reply was that it used to be 25 %. BAD SHE is not up to date with company policy. I was a loyal customer, not their biggest customer- needles to say they lost me and I will sprwd the news amongst Famuly and friens
