Selecting \Submit Meter Readings"does not work"""

Last month I tried to submit my meter readings via CSOnline but only 2 of my 3 meters are listed. So I phoned the Contact Centre. On selecting \submit Meter Readings"the automated system goes silent and never transfers the call. Tried again this month with the same result. I now have to wait for ages for the contact centre staff to attend to my call so I can submit readings."""
