Beware: Magnum Dynalab are not "doing repairs, upgrades or service right now"!!

Just a note if you are considering buying a Magnum Dynalap liner. After buying a factory box from MD, sending them my tuner in August, I was told verbatim from the Operations Manager that they are not "doing repairs, upgrades or service right now".  Six months went by and below is a sample of the items they told me. I am at a loss that they accepted the return for service, keep it six months and then say we won't fix it. 

• I will ship your unit back to you.  We can't solve you no power issue.
• If he can't fix it, I am just going to replace yours with a new unit.
• We are not doing repairs, upgrades or service right now,
• This is one we said we would look at in house and it is marked resolved January 8th but not shipped yet.
• Noted repair resolved "Cleaned the oxidized silver plated contacts in the switch cable inside the unit (inside the plug).
• Retested."
• Thanks for you most recent email from yesterday.  We will be looking at you MD90 the first ½ of January.
• If you don't hear back from me by Friday, please do a follow up and we may need to look at another service option.
• Hi William, we will have a better idea in a couple of weeks.
• We are in the works on doing changes in manufacturing so we can not touch repairs for at least another 4 to 6 weeks.
• It will be at least 6 weeks before we can start looking at this.  Please don't hesitate to reach out in 2 to 3 weeks for an update.

I love the tuners but be careful as it appears any investment would be a gamble... So odd for a company now owned by Bryson.
