If the phones do not work in the test socket then get an engineer out. The master socket and wiring up to it actually belongs to the phone company so if that is the problem then it is their responsibility to fix. However - you mention a socket upstairs, if fitted correctly that should come off the face plate that is removed from the master socket to get to the test point. If it has been bodged into the back of the test socket then you'll get charged!
