"Answer the phone!"

The work I have had done has been excellent. I have been treated with respect and am happy with most of the work done. However, yesterday I broke the tooth off the denture which was made for me 2 weeks ago. Firstly, I would not expect it to break so soon but more importantly, I have been trying to contact the institute to get some advice on what to do. I have spent over an hour on the phone, calling all 4 of the numbers on my letter. 3 of them ring out without anyone answering, the other one is dead. My only option is to drive the 16 miles to walk in to the building and speak to someone. I would rate this much higher if they just had someone answering the phones.
