A rude store manager.

I went to Build It in Mamelodi the one by Tsamaya Road, and everyone there is said to be rude and useless and ******. I wanted to exchange a gas cylinder and they didn't want to help because the packaging was open. Their till slip clearly states that the only thing they don't exchange is electrical appliances and that their exchanges are done within 10days after date of purchase. The assistants are *********** because they're the ones who sold us a wrong cylinder. Now their rude store manager tells me that I'm ****** and that he hates working with blacks because we don't see reason. I feel very violated especially because he was ready to call the police on us and he even damaged the packaging further and threw it in the bin.

I need urgent help on this matter... I need that rude store manager to be dealt with ASAP.
