National Express Swansea Cardiff recent customer reviews

Dreadful, awful, never again! The bus on outward journey went to another stand, didn't announce this fact and only mentioned the end destination which I didn't know as I was only going on part of the journey. Hence, I missed the bus and had to buy 2 new tickets with another provider. Tried to ask another national express driver for advice who told me it was my fault I'd missed the bus as I should have walked up and down the stands. He was curt and rude. Journey home was great. Will go with other company from now on as they were better organised
