Hi David, sorry I can't recommend you any pet sitters, but surely I'd never ever recommend you Branwell Mahon. This guy isn't really a pet sitter, he's just starting as he can't get a good job, so he has "cero experiencia" in pet sitting.
And if you are the kind of person who thinks it's fair to give newbies a chance to show they can be good, I used to think like you until I met this guy.
He's got two cats, one of them is very sick, but he (the pet sitter) hasn't been vaccinated against any animal diseases. His wife, the 'lovely porteña' actually seems to neglect the cat.
What is more, they're kinda weird. She is uneducated and can be quite impolite, rude and even agressive (and make a fuss if she's around) whenever you try to reach her husband on the phone.
In fact, she was the one who let me know the guy quit after they had an argument which I had the misfortune to witness, and he still owes me nearly $300 I paid in advance.
I'm currently sueing them. I would never give my consent to being treated like that.
All the best, Nadina.
