Rodwyn Dis-Chem

My story started long time ago this, they had a special for Comfort fabric softener, where you got 4 for R100, that was in July. they did a rain-check slip for me as they were out of stock. time went by and no call from them. Until last month I decided to go there to check what is happening. I was told that someone did call me. I told them that no called me, they went to their book and my name was crossed they said that meant that they called me so it is my fault that I did not come. I asked for proof that they called me, they don't have that proof. I was dismissed just like that by the store manager Rodwyn. this is Dis-Chem shelly beach.
