God point mariq7 , When it was 3 months it was good. I have had some sellers that I have had issues with and the time it took was more than 2 months.
One Polish seller sent me video tape via surface mail and it turned out to be a bootlegged / pirated copy. It was over 2 months and a bit more.
Another case was ****** ***, a seller in the US, a major seller of records and memorabilia etc.. One f the worst sellers I have dealt with. I purahsed what I was led to believe was a vintage hi-fi brocure pamphlet in near new cond. It was nothing more than 8 pages taken out of a magazine and in well read, I mean we read condition with fingernail impressions all over it. This seller doesn't refund on postage costsso I had to send it in to get a refund on my purchase less the postage costs. In those days USPS was a lot cheaper. I was still going to be out of pocket because of the sellers dishonesty / inability to see the difference between a booklet and pulled out pages / Inability to grade correctly. In the end PayPal stepped in with a once off offer to refund me completely and by-pass the whole process. In amongst all of this, the seller somehow put in some kind of a request for more money from me. WHAT !!! Yeah that's the second time it happened to me. 
Anyway, all of this, the attempts at negotiation, PayPal claim etc., having to return etc took more than 2 months.
BTW: This US seller frequently gets negatives for selling items with misrepresentation of what they are. But, with a high turnover and making a great living from it I guess ****** *** can afford to do this. Sadly, we the buyers suffer.
Once again mariq7 , you have brought up an important issue that needs addressing. Cheers
