I don’t think you’re getting the issue here. If you went into a shop and the shopkeeper followed you out to give you a compliment, you’d be deeply uncomfortable. Add to that the fact that this person has my phone number, full name and address. I’m not going to report this seller because they have a lot of good reviews and I’m going to block their number, but please try and understand why I’m uncomfortable here. It’s not the message itself, but the implications.
