As this is the Tips forum, it might be a good idea to include some actual tips!
TIP! If you're about to call an 084 or 087 number that you have called before, STOP ! Check the 'contact us' page of their website in case they have recently changed their telephone number.
TIP! If you're about to call an 084 or 087 number mentioned in the phone book delivered at the end of last year, or on some paperwork previously sent to you, STOP ! Check the 'contact us' page of their website in case they have recently changed their telephone number.
TIP! Some companies promote an 084 or 087 number for customers in the UK to call but also have a standard 01 or 02 number for use when customers are "calling from abroad". Replace the +44 with a 0 and you're away. You may also need to suppress Caller Line Identity.
TIP! If the organisation does not list any 01, 02, 03 or 080 numbers, check the sayNOto0870 website in case there is a suitable alternative number listed there. Once you get through, ask the organisation for a permanent 01, 02 or 03 number.
TIP! If you have only an 084 or 087 number to call, replace the 8 with a 3 and call the matching 034 or 037 number just in case it has recently been activated. Ofcom rules mean the new number will always belong to the same organisation.
TIP! If you're keying in an 084 or 087 number and relying on an app to find an alternative 01 or 02 number, STOP! Make sure you check the website of the organisation you are calling in case they have already replaced their 084 or 087 number with a cheaper 03 number.
TIP! If you usually call an alternative number such as the "calling from abroad" number or one you previously found on sayNOto0870, STOP! You will probably have bypassed any "change of number" announcements. Regularly check the organisation's website for updates.
TIP! If you're forced to ring an 084 or 087 number as there appears to be no other option available, listen carefully to any announcements in case there is information about a recent or forthcoming change of telephone number.
TIP! If you end up speaking to an organisation on an 084 or 087 number and the call is clearly covered by Regulation 41, inform them you require your "call costs over and above basic rate" to be refunded. From13 June 2014 this is your legal right.
