Shit happens

So…
Received a ticket in my bin about Microsoft word document. The person has VIP warning and it is marked as high priority.

So I used my lunch hour to solve her problem. Nice and smooth right?…

She called back while I am on lunch and one of the Team Lead told me that I helped her and then corrupted her computer. Now she is bitching about it.

I looked up her info…. Executive assistant. Someone with too much power and doesn't deserve it.

First of all, I am not supposed to handle VIP calls.
Second, if she's the secretary she's supposed to know how to do that in word, not making me do her work for her.
Third, Word document cannot corrupt a whole computer. I repeat word document cannot corrupt a whole computer.

But did I voice that? No. I just took it and say: “Sorry, I'll try harder next time”
I handle about 20 problem ticket per day and 155 calls a week. Which is 50% more than average and that was just my first week at the new position while I don't know what to do.
