Angry with my ID

Was soo angry with my ID this week. Giving me many headaches for the pass few days.

Previously, we had agreed on a payment scheme before signing the quotation.
The payment scheme is different from his usual payment scheme but he agreed.
Then when the payments come, he tried to request the payment as per his usual practice but we talk about it and he agrees with me.

This week Stevie came back and he request for additional payment again.
Didn't like that at all as I thought he was being quite sneaky about it!
As Stevie was rarely around, he was not aware and went ahead and agrees to make additional payment the following week.

The following Monday (only 2 days after Stevie agrees), ID called me non-stop for the payment.
Lucky for me my hp was low batt but once I reached home I realized he gave me 6 missed calls.
Finally, he managed to reach me on Tuesday.

First he told me the fabric I have chosen (which I have given him the code weeks ago) is too expensive and the fabric will cost $1000++. Was already quite mad about it cos despite me reminding him many times to check whether the fabric is ok, he decides to only check it now. Then, after saying that he still ask me whether he can come collect the additional payment the same night. What the hell is he thinking?? After making such a blunder he still ask me for payment and didn't even suggest a resolution!!

Got pissed off and decides to ignore him for the whole week.
Had to go look at Fabric again which makes Stevie was sooo unhappy.

Anyways, I should just calm down.
The house is looking fine and besides the above things that I am not happy about, the house is coming along just fine.
