Dear mom,
Good for you you have so many contacts. Lovely. But when you visit someone and they tell you they have a problem with WhatsApp - or anything on their device at all - DON'T YOU EVER PROMISE AGAIN THAT I WILL COME TO THEIR HOUSE TO FIX THEIR PROBLEMS. I already ate enough candy today. And if they were to give me money (rare, we're in the Netherlands) I still couldn't care less. If you're too stupid to fix the problems on your phone you probably shouldn't have any phone at all.

Look, if it's my grandma who's kindly asking me whether I'd sometime like to look at her tablet to fix it, or I just happen to visit her (once in a few months): sure, I'll try my best. But for a stranger I haven't heard about who just got here? NO. I don't know you so I honestly couldn't care less about your problems. Go ask your own grandchildren.
