Do you use G-Mail?
If you’re on G-Mail, you may not have received replies sent by Anna, or urgent booking messages. Google now thinks they’re spam, or even just refuses them! Go into your G-mail settings and ‘whitelist’ these two domains: polefitlondon.com and appointy.com. That should fix it for future e-mails (to see how in detail, click ‘more’ and then click here).
