I thought he want to clarify with me here?

Ok, thing goes like this.

One week ago, i wish to sell my 6600.
Then he asked me whether can trade with his 6230 or not. At first i tell him to sell his 6230 first, then only buy from me. But i don't know why, he said it's hard.

Ok, since he's quite sincere n he's from melaka too, so i decided to help him post the thread to sell his 6230. Ok, there's one forummer pm me(azrko), and said he is coming to melaka next tuesday to COD with me. So, on that night, friday night, i sms alvin ask him whether can trade on friday night or not. (he give me top - up and trade in his 6230 with my 6600, so i sell 6230 to azrko), at first, he agreed that meet on 9.30pm. But then, sms me ask me the price can cheaper or not. I said can't...Then i dunno why, he suddenly said contact me on monday...Ok, i replied him "Contact me on monday". I am quite frustrated coz i promised azrko to meet on tuesday....(at last i told azrko the 6230 is unavailable coz i not sure alvin still wan trade or not)

Now the 6600 already sold to other forummer..then just now he sms me that ask me trade on tomoro. After i told him that 6600 had been sold, he said i am bad seller and wanna report in LYN..

So...did i have any wrong?!?!??!?!
