Hello, it will be our pleasure to help you. Our company charges 50$ per each service fee and diagnostics. Most of the time customers are incorrect with the diagnose so we must inspect the issue ourselves. Depending on what needs to be done and the model of the object we will provide an accurate price. Service fee will be applied towards the final price if you choose our business. Once our technician is onsite he will provide and explain what is wrong. Let us know if you agree with the service fee by providing your address and phone number. If you let our company fix your facilities we will not charge you service fee. Thank you!
