I don't think they are dealing with it well - keeping people waiting for so long with no emails or updates to let us know we have not been forgotten about looks to me like they are just leaving things and can't be bothered to chase their suppliers or keep customers updated, and the only reason we know of for the delays is their incompetence and inability to keep up with the number of orders - there are no extenuating circumstances like the weather preventing stock from getting to them etc, just that they have taken more orders than they can send out.
I have always had good customer service from my current meter company, Accuchek, and this bad service from Bayer is really putting me off them which is a pity since the meter looks really good. What I would like is to receive regular updates on what they are doing to get the chargers out and specific dates when they will be sent, assurances that the suppliers are being chased up and ideally changed to avoid these problems happening again, and the same information available at the top of the front page of their website. That would make me feel valued as a customer and not forgotten and ignored, as I now feel. I know the charger is free but that is not the point - I would be happy to pay a few quid for it if I knew it would arrive in good time or I would have been happy to pay a little more for the meter if they included a charger as standard.
