HDFC Bank — home loan processing fee refund

Hi, this is gokula from chennai (Madhandhapuram) i have recently applied for home loan in hdfc bank through a builder who had bankers linked to them. Due to personal reasons i had to drop the project - file no.[protected]. The banker asked me to drop a mail regarding refund of the processing fee, which i did on july 14th and till now the refund amount (Rs.11, 615) is not yet deposited. Its been more than a month and the response from the banker is very poor.
Banker details:
Name: suresh
Id: [protected]@hdfcsales.com

Attaching the mail and debit screen caps for reference. Please take necessary
Actions.
Note: the eagerness in collecting the processing fee is not visible when the same has to be refunded. Very poor customer service, highly disappointed.
