Thank you for taking the time to provide us with sincere feedback. We are happy to hear that our customer service rep was great. We apologize that there was a disconnect and the cleaning service was not performed as it was stated it would be. The review will be passed along to management to ensure this will be fixed for future services. Thank you again for the feedback!
