Please take note of items which you buy

Back to Houseware and Sanitary Ware (Whole Story)
1stly, I went to Summer (S), they didn't have much range which I like except Barons WC, so
i ended up buying from Lucky Khoon (LK) instead.

(1)
Only to realised that LK overcharged me on mixers and taps even if it's after nego and discount!
(I only compared 3 items if I had compared all, there will be much more)

I got $400 refunded from the 3 items.
After which I used $430 to replace the 3 LK items plus a Basin
Royal Franco (RF)

(2)
After installing the WC, design is the same 1 PC type. I realised that how come the logo on the WC is so different from the one which I ordered. I realised that LK has given me another WC without clarifying that I'm actually ordering Barons. They were "smart" enough not to put the brand on the invoice and told us that they gave us that design because they didn't have what we ordered in Black. When did we order Black in the 1st place??
Have gotten them to change the WC to the one we ordered.

(3)
Not sure if installer were from LK, after installing my rainshower, I realised that my
tile is cracked, am getting the ID to change it for me.

What I have learnt:-
(a) Make sure they write every single item together with Brands (if any) on the invoice
when you order
(b) Make sure you check every single item before they install.

I was not there to inspect the delivery and by the time i check the site,
they were already installing half-way and I couldn't go in to check until they have completed all
the installation. I can only check the following night only to find out those issue above.
