Unprofessional and disrespectful

I would give this place ZERO stars if I could! My husband went to the store 2 weeks ago to buy a part and when he arrived the store doors were closed and there was a notification pasted up that they don't allow walk in customers and people have to phone or whatsapp or email their order - which does NOT make sense as the product you need to order, you need to bring a actual sample for them to be able to match it! Nevertheless, he called the number on the door to explain this to the staff and was rudely asked why he was calling this number. He explained to him that he was outside, he needs to purchase nuts and bolts, he would put the order online as indicated but he needs someone to look at the sample to guide in terms of the size. This rude staff member told him someone would come outside to help him and he waited for over 20 minutes for this person before calling the number again and remind them that he is waiting. He was rudely told that they are busy and he must just wait. 10 minutes later, a staff member came out and refused to help him and deliberately attended to people who arrived after him. He then just decided to leave because clearly they do not care about customer service. This place is absolutely unprofessional and completely disrespectful!!!! Do not use this place unless you want to be ignored or treated with the utmost disrespect!
