When I saw your title, I expected to read an irrational rant.
But it's hard not to be sympathetic to your story. While the worst repair from a customer perspective is one where the machine comes back with precisely the same problem, not far behind is one where they fix the reported issue and break something else.
I'm sure the technicians are judged on how quickly they can turn around a problem, but there really ought to be some basic tests of major functionality before a repair is considered to be completed.
exactly, but now i am unsatisfied with their customer services, they promised me will contact me and then they didn't keep their promise.
i sent an email to them to complain this thing, never get a reply
they promised me will sent me a update email, i never received it
they promised me they will call me, i still haven't got the call
i mean if a company it can't keep its promise, why should i trust its quality and turns out their quality did awful compared with when the thinkpad still belong to IBM
