I hate 0870 and 0845 phone numbers!
I know I am not alone in saying that I HATE 0870 and 0845 phone numbers!
Maybe back in the days when we did not have such a choice of free/flat-rate call packages they were OK. But these days, most of have an inclusive deal or use a VOIP solution such as Skype. As far as I am aware, NONE of these options include calls to 0870 or 0845 numbers. You are not doing your customers any favours by using one of these numbers!
If I'm scoping out a supplier for something or other, I will always choose the one who has either an 0800 or an standard (geographical) phone number over one that only offers an 0870 or 0845 number.
I realise there are some people who have not yet wised up to the cheaper calling plan options ... so why not offer a choice? Give out your ordinary number AND your 0870/0845 number!
