Bad service from management from checkers woodburn Pietermaritzburg

Experienced the worst service from checkers woodburn Pietermaritzburg. I bought a Wahl haircut /barber kit not realising that it was cordless and it did not have a charger.Due to the power outages I could not continue only to realise that once I opened the product to use it. I contacted the checkers woodburn store in Pietermaritzburg and I was told via telephonic conversation that the management would make a plan to accommodate me and refund me R200. As per the telephonic conversation I was told to come to the store and everything will be sorted out only to get to the store and the entire management was very rude. I clearly explained that I opened the product and I was not happy with the product. First of all the management was dishonest and they wasted my time. I am a very unhappy customer and I want my refund of R200 back, matter will be escalated to the Consumer protection Act of South Africa. The regional manager of checkers Pietermaritzburg needs to step up and sort the bad management service out from checkers woodburn Pietermaritzburg.
