Bought them from my local pro shop. However, there aren't really good skate technicians in my country. However, I've already emailed Jackson to see what would be my best option. Regarding the kicking of the heel, I dont do it as I've thought of the same thing.
They will likely refer you back to the dealer. Jackson has never been a skate manufacturer who (in my experience) tends to take charge of these situations. I didn't find them all that pleasant to work with.
Apart from that, you likely need a stronger boot, or a boot that sets your heel in better. I had this issue in boots that were too soft and too stiff. You can be bending them too much, or they can be so stiff that the inability to bend the ankles well puts undue pressure where the skate upper attaches in the heel.
Additionally, if your heel isn't set right in the heel (due to sizing, too steep an incline of the foot bed/too high heel, etc.) Your heel may be trying to slip up and pulling there a lot. Usually you'd develop physical symptoms by four months, though. Heel bumps/pain/bursitis, sore ankles and Achilles, etc.
Pronation/suppination can also be an issue as it sometimes leave room for the heel to bang into the boot which can cause a lot of pulling.
Do you wear any orthotics in the skates (even OTC)?
If the coach recommended a stronger model and the fitter agrees, the issue can be chalked up to normal wear and tear and they aren't really responsible for the problem.
The knot time a dealer has taken back skates for me (and I've gone through total 9 boots in < 3years due to issues when you count returned pairs) is when the fit just wasn't right (too long/wide etc.). In that case, they took them back without question and ordered in the right size.
Kicking the heels when putting the skates on does not cause this.
Edit: Terrible auto correct on this phone. Sorry.
Also, the Jackson Elite Suede boots I got were the stiffest boots I've worn, ever. They are stiffer than the Elite Supreme leather skates that I had ordered in before them. They have more lateral stiffness than anything I've ever worn, and unless you are doing tons of doubles and some triples make sure you try on a pair, hopefully on the ice before buying.
I did tons of doubles in mine. They still don't have a hint of a crease on them. I ended up moving to a different brand. The only boots I've had that I couldn't even began to break on. I usually get boots in the KT-3 and Report RF-2 Super range of stiffness, to give a base for comparison.
They also creak a bit when I attempt to bend in them, so they may be defective (the inserts for heat molding).
If you get Elite, get the leather boot. It's a bit less stiff. The Supreme is way more comfortable to wear though, assuming your feet fit Jackson boots.
