One of the problems in today's customer services is the feedback mechanism; the current options are either transferring the call to a feedback line after the call or sending questions to the customer via SMS/text. I never participated in any of these feedback requests.
However, feedback is important for any services so customer services is not an exception. NoTime offers a simple feedback mechanism to rate your experience from 1 to 5. You can also add notes about the specifics of your experience. This is a non-intrusive feature which is very important for the teams that are trying to provide the best customer experience possible.
