Pathetic customer service and misleading signage

I am appalled by the service levels of the Edgars store in Oxford Street, East London. The service levels seem to be going from bad to worse with utter disregards of customer service amongst the staff member. What is even more shocking is when you get a manager that is clueless about what they are saying to the customer and just babble sweet nothing. I purchased an item and clearly on the display a sales price was displayed, R1 49.99 and as usual during sales at edgars the price on the actual item is not the sale price. To my surprise when the item is rung on the till the price is higher than the displayed price and the cashier called the manager. The only explanation the manager could tell me is that the said item is out of stock. I informed him he is being economical with the truth.I informed him since he failed to prove any of this he is saying the difference should be deducted from my account and he blatantly refused and informed me to call head office. I said I want to lodge a formal complaint and then he gave me a customer feedback form which is something else. Im so disappointed at the manager on 03/42015 Lubabalo Mbalane because he is clueless. Customer Service sucks
