I'd even venture a guess to say that a company can and does have the ability to modify their ability to repair/replace/refund anything they'd like at their discretion. Your bullet points are a bit dramatic for this case. I did not once read the OP said Microtech would not repair their issue, rather there is a delay in that area. Crap happens, life going on.
Dramatic? I disagree with you wholly there those are standard policies that are used in Customer Service. 2.5 months is pretty dramatic to shut down a repair facility and deny all returns/warranty related work. Keep in mind I said deny, not put aside.
Crap does happen Rev, however as a mod who's seen countless bad transactions go down on the forum you should very well know that what happens after and how it is resolved (or left unresolved) is what matters.
Microtech is saying 2.5 months delay, then an additional 3-6 weeks wait? Totally up to 4 months, 1/3rd of the year. They have not offered anything else. That to me is unacceptable.
If you think standard customer service policies are dramatic, and you think 4 month wait is reasonable and not cause for concern. Well that's on you.
