It is now very easy to keep tabs on what your competitor is doing - you only have to watch their web site - and then you can follow (or lead) with prices and surcharges as you choose. Just make sure that you keep enough space between your prices and the dates when you implement them.
To actually speak to the competitors shows that these people were badly recruited and badly managed. i.e. Senior mgmt is at fault. But ... try to prove that in court? Ha!
