Extented warranty Changes in policy after sold

I bought a BYDesign TV from HIFI Corporation, and took the extended warranty. TV went for repairs 21 days ago. Firstly I was told a loan TV will only be after 14 days, Then on 16 days I was told it takes 21 days. On 21 days, now the policy changed and you just have to wait till the repairs is done. False advertising to sell extended warranties. Its now 21 days and no idea when the TV will be repaired as they have a system change too now. What is the new process? and can someone let me know what exactly is the new policy, as this is a breach in selling the warranty.
