MGM Low Voltage Cut Off - Owners READ

[potreinas]

I receibed my new 9032 with 3.21 firmware changing my bad 12018 that has instant braking.:

This is my case:
bought a 12018 esc 2 months ago, the esc did instant bracking, like someone has too here, I sed 1 mail, answered 1 dai after, ok, the 2nd mail from me to they.. last 5 days.
they "change" my 12018 for a 9032 one, paying the difference ( plus upgraded usbcom +, ccc03, and programming card)

I receibed it on wednesday, i soldered connectors and I DOESN'T WORK, the green light near the capacitors that lights when you connect the lipos... DONT LIGHT, it can be programed by pc or by programming card, but it doesn't work, I can't calibrate the esc with the radio.
I tryed with my 3pk with different spektrums, with 40Mhz FM, and also with a perfex 27Mhz, but it doesn't work.
I tryed with and without bec, with battery receiber, with neu, feigao, mamba max, motors bot NOTHING.

I sended to mg 1 e-mail wednesday night, thursday sended other, today I sended one more to ALL the e-mail I had from them but.. NO ANSWER.

Y pay more than 300€ (like 450$ by the money change), for an esc that not work. and they dont answer me nothing.

Also I sended a video showing the NO-operation of the esc.

Can someone tell me what's happening with MGM?

Sorry about my bad english, I'm from Spain, my english is very bad and I am very angry and disappointed.

thanks for reading.
