Dear Sir/Madam,
I am writing to express my profound dissatisfaction regarding the repair service performed on my MacBook Pro last week. My device was submitted to your branch on 12 October for a critical screen replacement after the display began flickering intermittently and eventually went completely black.
Upon collecting the machine yesterday, I was dismayed to find that the screen flickers even worse than before. Furthermore, the technician failed to secure the base casing properly, leaving a noticeable gap on the left side, and the internal cooling fan is now making a persistent grinding noise that was not present previously. It appears the device was handled with extreme carelessness.
I expect you to rectify these issues immediately by conducting a thorough repair at no additional cost. If the hardware cannot be restored to full working order within three working days, I request a full refund of the £250 service fee so that I may seek assistance from a certified service centre elsewhere.
I look forward to your prompt response regarding this matter.
Yours faithfully,
Jonathan Sterling
