Bad service by Mokheseng marks park

For the 1st time ever i got a bad service at tekkie town Vereeniging marks park, im super disappointed by the kind of service i got. I was assited by Mokheseng weeeee ai never again will i step my foot in that store. While she was giving bad attitude, the bag i got had a price of 549.00 i got to the till it's R599.00, told her i want to pay for the price that I see because there's a further R150 off the original price, she bluntly told me that it's impossible, i told her again that i want to pay for the price i saw, she kept quiet and continued with the purchase. I didnt want to cause a scene in store so i paid then left. So sad to see store assistants acting the way she did, the price is not corrected because no1 wants to do their job!!! I hope she sees this and changes her attitude cos it stinks, and her collegue chewing a gum loudly OMG worst service ever.
