Good morning everyone, update till today:
Seller has not replied to my SMS nor sent us the 2 missed notes he promised

I should have been more careful when he asked for my name but did not tell me his name.
When he listed the notes are bounded but then he said he had to get the notes bound in OW only on saturday.
When he said he took out the notes from being bounded for exam.
The notes looked freshly copied (the highlights does not look original).
He listed complete notes for sale and I reconfirm with him to bring complete notes but after checking note 13 & 19 were not there. We still paid him bec he said "promised I will email you the notes".
And what make me angry is on saturday my 85 year old grandma, my parents and I went to OW to wait for 50 minutes bec he said he was getting his notes bound there (then he said it was long q and decided to sell to me without bounded for reduced price). Did he go to the OW service counter to get back his notes? No, he came in with the notes.
Then excuses after excuses why we still did not get the notes. These are his excuses :"Crap did I send it to wrong email?"
"I am not at home at the moment

" but yet you can see him online here on AN (the green button was on).
I am writing this down to remind our young fellow ANers and myself in the future don't simply trust anyone.
Hopefully good news from our very friendly moderators soon.
