Mr Muck review for Zapiet ‑ Rates by Zip Code

App has gone down in our peak season, stopping sales whilst £1000's are being spent on advertisement, no notification of an issue when there clearly is, telephone line has no answer, so the only option is email. Considering how important this function is, especially when the margin between a sale & losing a customer is so small, you would think that they would have an easier route to raise immediate issues, rather than having to wait for a few hours for a response. Very disappointing....
