Thanks! Angela
Olson + Baker were wonderful to deal with.
We purchased our item (a beautiful coat hook) but had to delay delivery due to a trip overseas.
We weren't dealing with an automated system, just real people who cared enough to help.
It has been an absolute pleasure buying a lovely piece of furniture from Olsen + Baker. Russell has been a delight to deal with, keeping me informed at every step of the delivery, even down to which colour would fit with my decor - nothing was too much.
I can’t recommend highly enough.
Really excellent customer service. Can not recommend this company highly enough - the products are high quality and their communication with the customer is first class. Jonathon always responded promptly to any queries and was very helpful.
I would definitely buy from them again.
Fantastic customer service throughout the ordering process.
