Call centres are meant to provide telephone support to customers in different industries. For example in mobile operators industry, call centres use to provide needed support to their customers to use products and services which generates revenue for operators.
But I understand that some of call centres, due to large number of calls they cannot answer, started to charge call access to support. Well, there are different markets, reactions, provided support etc and this call charging concepts are probably different. I would like to find out more about call centres charging concepts, how are they charging, do they charge to all customers or by segments, by number of calls, by type of support, what are they communicating why they charge for support etc.
Thx for answer in advance!

I'm sure that these charges would be a closely guarded secret due to commercial pressures.

I'm not an expert on this, but I'd thought you'd like to know that HSBC (a bank here in the UK) has caused a bit of a stink on two fronts;

Firstly, they have started routing calls to call centres depending on how much money you make, and thus how much money you make them. Rich people get their calls answered in the UK, poor people (like me!) get directed to India! You can read more on this here;

Secondly, they've started to clamp down on who uses which banks, again on how much you earn! So if you're poor, you can't use certain banks!

Hope that adds to the conversation!
