false advertising and conflicting management responses.

i have always compared prices online among stores before i go out and make a purchase. Always been the case with me. Today was no different. I searched for scrubbing brush with handle and the Academy Brushware F4055 showed up as R75. I went to Rossburgh despite me saying I will never set foot there again due to **** service and previous hellopeter complaint. I chose the item and was scanned R135 at the till. Upon my query, and indian lady with glasses (supervisor) told me to purchase it online and collect in store. This sounded weird. I told her that i do not have an online account. In the meantime the cashier called for Kimishka who in turn told me something completely opposite to the previous supervisor.. she said i will not be able to get this product at the price and i will need to order it online! I then told her i will pay the R135 but while im at the till i will post a hellopeter report and while saying this, she discounted the item to R75! Why did she do this if she was so sure that she was right?? Is this an admission of guilt or fear of the hellopeter complaint?? Why does 2 superviors give conflicting responses? No training perhaps? How many other customers are being ****med in this manner? At the same time of my incident there was another irate customer at another till also threatening to report his issue on hellopeter. Builders Rossburgh should really shut its doors! Today was my last day i set foot in that **** place! Never again. I hope this post hits them where it hurts the most. Their bottom line!!! Enough is enough.
