a word of legal advice.
if the due amount (to dialog) exceeds three years with the following conditions
1. they have not sent a registered post letter to you... which you accepted within a three year period.
2. You had no Written contact OR contract (note the R) with Dialog for the past three years agreeing to "pay" the due amount or any reason whatsoever to with it
3. If you had not made any other form or sort of a written undertaking to pay the due amount.
According to the law, that due debt is now null and void.
so., in other words.. you call dialog and just say "Go fuck your self"
but.. if any of the above three things DID happen.. well., you are tied to pay them
