Customer Question

Customer: hi my name is ***** ***** we have a sentry safe v330 serial number u3505788 with a key and combo and we can't get it open has been sitting.
JA: Thanks. Can you give me any more details about your issue?
Customer: we called sentry and they told us that the first number in our combination was wrong but this is the combo we have always used.
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to Home Security Systems Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?
Customer: yes
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
