Hi Mayra,
I have no experience yet with High on Leather however a quick research on Google would give blog (sponsored) results re: the website. So far, I have seen 3 latest posts and saw that they have a Facebook page, Instagram page, and I even found a link for LinkedIn supposedly would be for the founder of the company. Given that they have managed and maintained the accounts for years, then it may contribute for them being "credible"however, that is not an assurance though. If I may suggest, you can try to contact them directly and check on their policies so you can weigh if they are trustworthy. Do take note for first impressions such as the timeframe for them to get back to you and the details of their policies as well. Anyhow, you may also check on the results I have drawn c/o Google.
