Multiple brands with same name

[Simbiat]

I knew that at some point I will find a brand name, that is used by multiple unrelated brands, and I finally found one: Mastertech. Tablets are https://www.falabella.com.pe/falabella-pe/seller/MASTERTECH. and TVs are https://mastertechhome.com/en/productos/, and they do not seem to be related in any way (or at least I was not able to find obvious evidence of relation).
So question is... How to deal with such cases? I mean, how to "separate" them?

as an option

I think we can use the full name
MASTERTECH S.A.C

RUC 20600221761

if look at the products, the logos are very similar

S.A.C. stands for Sociedad Anonima Cerrada, which seems to be like Ltd or Inc or whatever, so not really part of the name. But even if we do include S.A.C. - then why exclude Grupo? But what's more, it would still be a temporary solution until we get 2 companies which are fully identical even with their full corporate name. I'm not that savvy with legal aspect of company names and trademarks, but if I understand this correctly, you can a company name along with a unique logo, and it will make it will be considered a completely separate and totally valid entity as a company with same name and no (officially registered) logo or with same name and a different logo.
I think we need a better way to differentiate brands, but I honestly have no idea how exactly, especially, if we want a maintainable way.
