Walmart - Tire & Lube Express

I went there to this walmart to buy chicken with price match and you will not believe they send me to 3 cashiers to do price match because two other cashiers doesnot know how to do it ,than third cashier whose name is Winston charges my credit card more with price match. I bought 3.3 lbs chickena nd price match was 1.99 so it should be $6.60 and he charged me $7.60. When I corrected him on this he told m ego to customer service and correct it as this is his time to leave. This was his mistake and he wants my time to be wasted which is already wasted by going to 3 cashiers.Than when I asked for manager there is a girl Amy came and she introduced herself as manager. Once I explained everything to her she says he will call manager. They donot know hwo is manager and they donot care about customers time. This wal mat definately needs to hire experience people rather than employees who has no care for customners. Walmart advertise themself as price match with other stores and that is the only reason we go there for pricematch. We are not buying things free so we deserve best customer service. I always do my shoping from walmart even if I go for vacation I look for walmart near by ,I never had this kind of worst experience before.
