Like I'm sure many of you are I am feeling a bit fed up with my lungs atm. If I could I'd complain to the manufacturers, like this:
To Whom It May Concern,
Re: Lungs
I purchased this product from you in October 1985 and I have to say I am disappointed with its performance. I was told the predicted lifespan of this product was approximately 80 years, and it began to malfunction after just 7.
Though your technical support handled this problem well and I was able to use the product without any serious issues for several years, I have not been at all happy with its performance within the last 2 years and its recent function has been appalling. It is no good your technical support telling me that the numbers show this is a superior product and therefore must be working well, nor that I must be using it wrong and if it's not making a funny noise there can't be anything wrong with it. I have been using this product for 25 years and I know when it's not functioning properly, even if I need help troubleshooting (and no, I can't turn it off and back on again).
Furthermore, the product is beginning to have an effect on other parts it works with, requiring more calls to other areas of technical support. Your technical support team is for the most part very efficient and dedicated, but I would rather be spending my time doing something else, even if some of the calls do give me a perfect excuse to buy ice cream.
I would like an immediate replacement of the faulty parts and an assurance that this problem will not reoccur.
Thank you.
Yours sincerely,
Philomela
