GSM-Forum - 3 dead clips, no answer from support

ive been having issues with these things since they came out, on my first box it started off working fine then stopped working displaying "check keycard failed" as it would if a java card were out of credits, i tried to update through the client but all options were greyed out so i reimaged the card as suggested but the error persisted, i ordered another clip as i needed to do the job as soon as possible and messaged support staff here about it, soon after they did get back, ask for my clip ID and i had to reactivate the box (they had re-enabled the activate option in client) it worked again

a few days later the second clip stops working in the same way "check keycard failed" again i messaged support and the clip was reactivated, skip on a few more days and one after the other both boxes start giving "check keycard failed" so once again i messaged support, no answer, messaged again, no answer so i contacted my reseller who sent me a replacement box, when that arrived i attempted to continue unlocking but this clip too just gave "check keycard failed"

What is going on? why do these clips seem to run out like java cards do? and why are the support staff suddenly ignoring messages on the issue? and if simply reactivating it fixes the issue then why not just leave the option open so we can fix it ourselves?

ive tried everything i can to get it working again, reimaged them with the image in the sticky post, tried reactivating but not allowed and updated when i could but still nothing. just in case it is of any help i tried to run a fastboot oem writesecureflag 0 with the clip in the device, the result was this:

fastboot oem writesecureflag 3
