there then followed a short conversation that amounted to that - given that $mydomain was working fine, they would *not* look at the problem for $contractorsdomain unless $contractor contacted them about it.

You can hardly expect an ISP to change an MX record on the opinion (right or wrong) of a third party. It could be someone trying a little social engineering. The customer or ISP could be in the middle of some DNS changes. It could be someone talking out of their backside. This kind of request for change needs to come through the proper channels from the customer or their nominated point of contact. TT
