HDFC Bank — home loan disbursement delay

Address:

22/7 Mettu St, Chittibabu Nagar, Kolathur,, 22/7 Mettu St, Kolathur,, Chennai, Tamil Nadu, 600099

I was interested to transfer my existing home loan from nationalized bank to private bank with top up loan facility. My both loans was sanctioned but not disbursed since last 4 months. There is no response over phone. Visited main office and branch office regularly. No solution provided. Its a mental harassment for me after paying processing fee for both of my loans without disbursement.
