Surprised and disappointed by bad service

Previously had good service so I returned. This time, I have been let down. Terrible service, response time and miscommunications about where my laptop is and what the fee actually is (of course I'm frustrated which is aggravated by obstinance on the phone). Today is 14 working days on and I still don't have my laptop back. In addition, I have been told since I failed to turn my laptop on in store to show that it was working, they will not cover if laptop has further damage (I sent it in for a quote on a broken hinge and sticky keyboard - which, granted, is from a juice spill but the laptop has been working perfectly for months up until I brought it in to get a quote on the hinge and cleaning). Now I've been guaranteed my laptop will be back by tomorrow even though I leave the country for a month tonight. Like I said, on the phone, maybe I can't make anyone pay if the laptop has further damage (which is an unknown at this point), but this is more a report on appalling customer service (which led me to become quite rude on the phone, I will admit to this line: \I effing hope you're on Hello Peter"."""
