My friend ordered a China 'Samsung Note' look alike smartphone... he wanted a 8GB version... and was given a 4GB version (he didn't check)... return to the shop.... was 'Given' a 16GB MicroSD card instead of the right phone...
I do buy from SLS. But only from the good shops. You have to know the territory.
The blacklisted shops do not care. How many tourists and shoppers know of such a list and bother to check it.
Let us say it is 2 out of 10. Then the bad shops can still make a killing from the other 8 out of 10. Statistically, they win.
From one of the vendors:
"They put one list (sic), anyhow say we are cheats, so of course we fight back. I have been doing business here for over ten years, not so easy to get rid of me," said one vendor who runs a shop selling second-hand mobile phones.
