Paid unavailable Black Friday promotion item at OK Furniture and failure to resolve the matter

Good Day,

On Black Friday, I paid R3000 to buy a base set which was on promotion from OK FURNITURE Sasolburg branch. I was told the base sets were out of stock and will be available within a week time and they will notify. In 2 weeks time, the sales person contacted me to inform that the respective base set is completely out of stock from the warehouse and can not be retained from any branches and advised that I pay R200 extra to get another specified base set which I then requested to pick it up from Pretoria branch since I have already moved in to Pretoria and she agreed. When I got to the Pretoria branch and they followed up on the matter, the sasolburg branch supervisor indicated that I was given a false info by their sales person since I can still get the base set I bought but I should wait until Pretoria branch regain such base sets. This was more confusing and the Pretoria branch manager decided to call the Sasolburg branch manager for more clarity and direction in which she confirmed that the kind of base sets I bought in BF were no more available and the special for another selected base set which needed additional R200 was a one day special and was no more valid. I indicated that the sales person has never mentioned to me that the special would last for just one day. Sasolburg branch manager confirmed that she cant help me any further and cant talk to me as the PTA manager recommended that she talked to me since I was never given the correct info by her staff and perhaps she provide the direction how to move forward. She then hang on the phone. Subsequently, I have been sending emails to OK Furniture Head quarters two weeks ago to request their intervention to resolve this matter. Until now, i have not heard any feedback neither from Head quarters nor to Sasolburg branch....This is an unfortunate treatment and poor services I experienced from Sasolburg OK Furniture. OK FURNITURE needs to deliver as promised/reimburse since I could have had an opportunity to spent that R3000 appropriately at that special day. Its important that stores manage the Black Fridays in a proper way to respect their customers equally to their gain. Please assist me to attain justice in this matter..Shirley...***
