Broker commissions in Ghaziabad are a total scam, aren't they?

Kisi aur ko bhi laga ki broker ne sirf commission ke liye deal karayi? I just got possession of my 3BHK in Gagan Vihar from Treasure Homez. Mera broker bola tha ki all-inclusive price hai, but ab maintenance aur other charges mein galti dikh rahi hai. He pushed for this new project when a resale unit was probably better value. Yaar, secondary market mein kya deal better milti hai brokers se? What did you guys do? This whole process feels like a scam.
