It is the government of your country that appoints their member for the Commission. If they appoint shitty ones blame them. For example the current Finnish representative is Jyrki Katainen who is the previous prime minister and his party (Kokoomus) is still a member in the ruling coalition. Even though he probably isn't the most liked person anymore (his prime minister era didn't go that well) he is still well liked within his own party and they probably traded some minister seat for getting him into the Commission. Shit is politics like always but I wouldn't go as far as say that the EU is undemocratic. Also the ability to speak English isn't that important in EU level. All the big EU institutions are in Luxembourg or Brussels which pretty much makes French and German the main languages. Still there is plenty of translators available when needed. If Germany wants to keep sending Günther Oettinger as their Commissioner then the only people you can blame are Merkel and her party. Again democracy. If it matters to you make it a point in your elections. I know most people don't as in my experience most people don't have a clue how the EU works. Many of my friends think the Commissioners are just appointed by some elite instead of being each country sending their own just like the head of state is in the Council. Still you can't call a system undemocratic just because people choose not to engage in the process.
