Worst Service at Woolworths Rosebank

I bought some promotional bedding with 20% discount and I bought a wrong size and when I came today to do the exchange Nthanyiseni advise me that I cannot do the exchange with the discount since the promotion is over, she did not even try to give me options since this is customer service environment.i asked to speak to the Manager her name is Thandi Dlamini from Home Department advise that she cannot assist me, she did not even listen and come with ideas on how we can sort out this issue. I stay in Emmarentia and I had to drive all the way since I was advised that they have the size and they will not be paying for my petrol to come all the way for such nonsense. Now I am advise that they cannot assist. This is ridiculous service Ive been loyal customers for Woolworths for years my family and friend were introduced by me and we are loyal members here. What I love the most is there customer service and always going beyond the customers needs.But I guess this has changed with this being the worst Service i have ever received from Woolworth ROSEBANK. I am appauled by this service I’ve shopped here for years and this one is the worst one I’ve received thus far.

Can I get a solution to this issue above or please advise me if you don’t need my business anymore
