Tip #2: Ask for the real price! Confusing price quotes? Beware of falling into the "price trap"!

Pilgrimage "Telephone Diagnostics

When you call them, they can already tell you that "the motherboard is burnt", "the computer is poisoned", "you need to replace the spare parts", and even quote you an astronomical price before you even look at the machine.
Professional maintenance can never "beat a bull from a mountain".
Just as a doctor will prescribe medication only after seeing you personally, a real engineer must have physically inspected and tested the equipment before he can determine the problem.
99.9% is your home visit fee and your checkup fee once you are diagnosed over the phone!

Threatening Sales

When you think of not fixing it, the other party will say, "Your family photos and work documents are so important! If you don't do it, it will be gone!"
This is the most despicable sales tactic, which is to exploit your fear. Professional companies will provide objective data recovery solutions and charges, instead of blackmailing you with your precious memories. They want to save not your data, but your wallet!

Big secret - no parts have been replaced at all!

After I paid the money, it broke down again a few months later, and when I opened the case, I found out that *your old* parts had not been replaced at all! The other party argued that the bill was for "repair" and not "replacement".
It is the highest level of fraud. To avoid this, it is important to choose a reliable company:
Request for return of old parts: If a core part (e.g. motherboard, hard disk) is replaced, you have every right to request for the return of the old you.
Clearly written invoices: Always ask the invoice to state "Replace with new parts of XXX model" instead of "Repair XXX".
