Terrible customer service from the very start!

They showed up 40 minutes late to a rental viewing, but did not bother to call to let us know about delays - I had to chase them up (we were relocating and had driven up from south Wales especially for viewings). Failed to email over paperwork when they said they would (they eventually sent it over two days later than promised, but again only after I chased it up). They refuse to answer the telephone or acknowledge that they've made mistakes. Unsurprisingly we've since decided that we won't be renting via Cowell-Norford. Very shoddy customer service indeed.
