Ring Doorbell Pro - Activating Chime Intermittently

Hi, Ring Doorbell Pro Wired, 3 years old. Chime now only activates intermittently. Have reset Chime and still problem persists. The button on the doorbell appears to be perishing. Having paid £229 I don’t feel this offers good value.
Do Ring offer any discount on replacements in events like this?
Having now entered the Ring eco system I’m now a little tied in! Thanks.

Hi @user39135. Is this a hardwired Chime Kit, or a Ring Chime? At this time, Ring does not offer any discounts.
