NO REFUND OF MONEY FOR GUARANTEE PLAN. Review on Housing

I have Purchase Housing.com Guarantee Plan to sell my property. They said the package is for 120 days and if the property remains unsold they will give you moneyback(Not mentioned any service charges which is Rs 4999+GST). Now, even after one month of expiry of my package, I have mailed them many times, also tried to call them, but the call is placed on IVR and gets disconnected, so there is no customer support available. You only have to mail them and wait till their reply. After so many emails, they gave the reply that you are not eligible for a refund as property is sold through external sources(there term & Conditions which was not tell by sales executive while explaining the package details). My property is still unsold and I am tired by mailing they and waiting for there reply. There is no proper communication. Zero after sale service. they will call again and again to sale their plan, but no one executive reply for the problem you faced after the plan purchase. The housing owners package is a big scam, so requesting all do not pay for any service otherwise you also lose your money.
