I have had a BeoCom 2 for some years now and have not had these issues personally, although I have seen the charging pins stuck in a few times on other peoples phones and in every case I saw, it was because there had been some minor damage to the base, the plastic surrounding the charging pins had been knocked out of shape restricting the movement of the pins.
One thing I would say is perhaps you should be looking at this in a different way, rather than beeing dissapointed, be happy that your BeoCom 2 can be serviced after 4 years. I am sure there are not many phone manufacturers that can say that.
