Bad service recieved when i raised issue regard belt of un acceptable quality

I am unhappy with the quality of a belt bought at Woolworths store Kempton around September 2017 and I went to same store seeking a replacement. The belt frame doesn’t hold tight with prong and which is always untighten every time when am walking in public and that the reason I visited the store 0n 18/01/2018 and I raised the belt is not of acceptable quality. Both store Manager (*Sphiwe Lamola)and Core worker never believe what I said they keep on asking me if I bought the belt on same store and they were more defensive and even take the different belt of different value ,different frame and length using the code to justify that I have cut the belt that on the store. The store manager refuses to exchange the product under the worst assumption that they pick to cover their situation. I felt very shame and helpless in the manner that all the Manager and 2 staff member in present profiling me as **** and manipulator of the system provided that I explained that belt always lose the condition because every time I have to adjust it and being told that I pick the wrong side like I don’t know how to dress I found very humiliating and annoying to be depicted like that in my life. Though I will stick with belt I will never set my foot on that store anymore.
