It's not so much that the customer service people are advantaged/disadvantaged or helpful/unhelpful that, in my opinion, makes it a compete waste of time ringing them. It's the fact that they have no real ability to solve any of your problems which are not down to error on your part.

The turnover of staff in call centres is continual and few people last long in the job. So the person you speak to is doubtless barely trained, knows nothing much about how the company works and, when speaking to you, is working from a script along the lines of _"Customer has problem A -- Suggest solution B"_. So is highly unlikely to be able to do anything to help you, if your problem is not on their script --and they have no authority to make any decisions beyond the most standard basic procedures, anyway.
