You should have called him. It isn't incomplete. You have Oriel. As you have an Oriel, the work isn't as simple as it was for my car. You have to be VERY CAREFUL while getting it done as they shouldn't be messing with the airbag. Ask them at least 10 times if they have done it before in an Oriel. Rest, it should be an issue.
Bro, you can totally put the nonProsmatec sticker on. It's so nice of you to ask for my permission however.
People have put these stickers on their rides without asking. I shared a picture on the 26th page. 
But, you'll have to make the sticker yourself. If I would have been in Pakistan, I'd have made you one. It isn't that difficult. Just need a regular Prosmatec sticker and replace its "o" with the sign. You can get this sign made by any number plate wala or like me, you can make it yourself. Use the same "o" in "non". Traceout half of "m" from Prosmatec to write "n" in "non" so that the fonts match. That's it!
