How to contact your after-sale service division?
Wuhan Rayoptek Co.,Ltd provides quality after-sale customer support on several channels. They are email, phone, live chat, etc. Details are listed at the Contact Us page. Here we give you some pros and cons of these online customer service channels. Email can be frustrating if there is a lot of back and forth required and Phone support can be very time consuming and costly. So we recommend Live chat most. It is a good mix of email and phone support. It makes back-and-forth less cumbersome by allowing our after-sale service teams to hash out issues in real-time without the necessity for long phone conversations.
