Vodafone India — Refund of security deposit

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201310

I am vaibhav aggarwal, holding vodafone postpaid number: [protected]

Which i got port out to airtel against which security deposit was of rs.400/- which i was supposed to get after 45 days, now since more than 6 months have passed i have not received the same, after visiting vodafone store at alfa commercial belt, greater noida. They told me that "your cheque is returned due to incomplete address", how is it possible at the time of sending bills, they come on time.
They said that they are filing the request for cheque to the company and i have to check after 2 months, after 2 months when i get there they told the same to come after 2 months. After 6 months finally a cheque came from vodafone of rs.254 . I had waited for my money for 6 months, gone 4 times to the vodafone store waiting for hours over there due to token system.
So now do i have to wait another 2 months or file a complaint against vodafone?

Is this how they deal with the customer who leaves there company?

Please resolve the issue as soon as possible. Else i take any further actions.
