I'm raising Cain with smy and ecig.com

I love the sdna 75 form factor and operation, but suspect I have a failing board, intermittent, multiple, resistance change messages when I try to fire the device, with values that aren't close to my actual resistance.
Opened the box on the second SDNA, and that one had a badly glued magnet which came out first time I opened the battery door. 2 minute fix if they would just get me whatever glue they want me to use (if I don't already have it).
I reach out to ecig.com, am told they only cover the first 30 days, that I needed to go to smy. I send an email to smy in China with no response. I dig up the smy USA repair site, log a ticket with them and see their policy, written, clearly states the seller is responsible to set up warranty claims for 6 months.
Email to ecig.com, they offer me an 85% store credit. I respond back to them, with smy USA and evolv (since I do believe the first unit is a bad board), saying I expect everyone to get together and honor the warranty, I don't care how, I expect two fully functioning pv (and note I'd be happy to glue the silly magnet in) .
SMY repair center in the USA finally sends me something from a real person, saying "whoops", that he'll work it.
I do play nice, but won't be jerked around.
We'll see what happens, but I expect a positive result
