Great help with faulty products

I work for a pre-primary school and we have to have door bell. I purchased one from Build It and it stopped working within 2 weeks. I took it back and asked them to please open the next one so we could test it in store. I was helped by Dewald who was super helpful and patient. It seems many of the bells in stock were duds and we eventually got the 4th one to work 100%. After almost an hour of cutting open packaging, changing batteries and pushing buttons, I left a happy customer. Thank you to Dewald for the great service.
