Where is the safest place to buy a legitimate signed Messi jersey? NOT ICONS

I’m looking to buy a signed Messi jersey and want to make absolutely sure it’s authentic. I’m in Canada and would prefer to buy from a reputable source rather than take a chance on eBay or an unknown seller.

For those who collect Messi memorabilia, where would you recommend buying from?

I refuse to us Icons - I bought a jersey, site crashed. Went back a few days later and the price went up $500. I’ve tried calling and leaving voicemails but apparently they can’t be reached by phone. I’m so incredibly annoyed but their lack of customer service

TIA
