2 digit area code reference

The welcome pack which you should have received from VM prior to install would have included a paper contract. The contract would list, three digits long, for example, 011. Just remove the 0 and you have your two digit area ref. number. Also, the 'contract number' on the contract lists it. For example (fake contract number): 011/123456789/1

Some posts here suggest that your area ref. number could be 14. Give that a try.

And a tip of the future, if calling in from a number that is either not your contact number for VM or your VM landline, go with the account details path, either key in nonsense or or key nothing in. After 2 failed passes/nothing put in twice, it will let you into the main menu. Which is helpful if you ever forget your account number/area ref and need to call in urgently for support.
