Terrible service from Woolworths Baywest

I'm so dissapointed at the service I just received from Woolworths.

On Tuesday I bought at travelling mug from Woolworths Greenacres. It was used yesterday. I've put it in the dishwasher last night, and when I took the dishes out this morning, I saw that it cracked. I took it to Woolworths Baywest as its the closest and its the shop I go to on a weekly basis. I'm a regular customer there. When I showed the lady, she said she needs to go and call a manager, Reigardt. He came and said they first need to find out if this is dishwasher safe. After about 10 to 15min, then they came back and said they checked on their system to see if they had others returned it. So when they checked they said no one returned it and have to ensure it is dishwasher safe as they somehow looked as if they dont believe it is dishwasher safe. After they confirmed it is dishwasher safe, Reigardt said he cant help I must now be referred to another manager Dane. What an arrogant man this Dane is. He came back after another 10 - 15 minutes telling me this is dishwasher safe but its clear i let it fell. I asked what???How do you mean I let it fall and come and lie. He said first of all, if there were similar returns then he wouldve believed me, but since there had not been such returns it mustve fell. I told him I have integrity and I wouldnt lie about such thing. I felt like such a fool in Woolworths as Dane and Ashante(the lady that wasted my time) made me feel like a **** the more I tried to explain to them. I took the mug and left the shop. I would never go to Woolworths Baywest again. When I told them I will log a complaint on Hellopeter, it was as if they almost bursted out laughing, which tells me they did not give a damn about giving me service.

And in future I would rather go do my groceries at Checkers. They also have premier brands.
