Videocon Industries — failing to refund the mistakenly deducted amount from d2h account

Sir,

I am using videocon d2h services for the past 15 months.
Customer id is[protected]

Recently i relocated my residence and i had raised a request with you for the same.
Relocation was completed successfully on 09 sep 2018. I paid inr 500 (450 relocation charges as informed+50 for extra length of cable) to the technician who visied my house for installation.
But, my account has been debited with inr 400. I had spoke to the customer care supervisor multiple times for the refund of the amount for the past two weeks.
Still there is no action from your side. Everytime i am the one who has to follow up for this issue.

I request you to take proper action asap.

I have spent so much time and money to follow up this issue along with the mental stress.

This issue requires a fair consideration and compensation.

If this issue is not resolved at the earliest i would be taking necessary legal action against you for your irresponsibility.
