Was trying to get hold of 3 yesterday and got a couple of wrong uns on the page, so I've gone through them all and there are updates on these numbers...
From CONFIRMED NUMBERS:
Working with more info:
01442 456050 - If you type in a business mobile number it will put you through to Business CS. (Replaces an 0870 number I can't find atm)
01442 456400 - Is 3 collections department (aka payments), not customer services.
Not working:
0800 3586795 - reccomends calling 0843 number
+35314325020 (Irish No.) - The User that had subsribed to this service no longer does. If you wait it transfers to BT Corporate customer services but I don't know what number that replaces or how long it will last.
0141 2048674 - Connects for 5 seconds then cuts you off. Listed under 0870 7330432 in the text comments
NEW:
07782 333337 - 3 Business CS (All 3 shortcodes can be dialled via 07782 333 *** where *** is the 3 shortcode from a 3 mobile, though you've probably already guessed that!)
From UNVERIFIED NUMBERS:
Not working:
0800 3584839 - "Sorry, The number you have called is not avaliable"
Working with more info:
0800 3589341 - 3 Sales. Can be added to sales entry in confirmed.
01628 765000 - Can be amalgamated with the other head office numbers (its in twice at the end of the Confirmed numbers, can be made 1 entry.)
01933 778633 - Straight to contract CS menu
01442 456050 - Same as entry in confirmed numbers under Mobile Broadband support. Works.
0800 3589149 - Sales - can be added to sales entry.
Hope that makes sense!
