Stamped Reviews & Loyalty

I don't often leave reviews however I feel like I have to given the negative experience I have had with stamped. The customer service team stuffed up the migration of my account from a different platform and continue to deny any wrong doing- customers have been sent review emails from 2017 and with different settings that what I have customised. They quickly tried to hide the mistake however I have proof of the wrong emails from customers directly. It would have been much more professional to address the mistake so that a plan could be made going forward. As a business owener, I don't appreciate covering up errors being sent to my customers.
