Wrong name on birthday card!

[hondagirl500]

Husbands mum has a name that is a shorter version of mine (maryann/mary … lyn/lynsey) type thing.
he likes to use Moonpig for birthday cards as it saves him the effort of going to shop, post office etc.
last year, my birthday card had the short name on it. I always use the long version!! He had obviously clicked the ‘wrong’ name on his moonpig app. I pointed it out, laughing, and thought oh well no big deal. It was my birthday last week.
same thing…. Now I am annoyed.
once is a mistake, twice is just stupidity.
Aibu?

i dislike Moonpig, I’ve always thought if your going to use them then I’d rather not have the card. It’s so impersonal. It doesn’t take much effort to nip to a shop to choose a card and actually write in it:

why doesnt he address the cards to his mother as mum? That would help solve the problem!
