In English’s defence, it’s not an English word. It’s a German company named after a Spanish name. And at least to my ear, the Spanish and German pronunciations also have 3 different Es. One helpful Redditor also provided an IPA guide to the German pronunciation, agreeing with my ears:
mɛrˈtseːdɛs
The “e” in the middle is long and stressed.
Edit: I would also say, that most of the times it is even pronounced like this:
məˈtseːdɛs
But I can’t even begin to justify the letter c sounding like /s/, /k/, and /ʃ/.

Don’t know about other Germans but for me, the last e is a schwa. So it’s more [mɛɐ̯ˈtseːdəs] I think but I’m not completely sure.
