I opened a Service ticket with Thomson on 22nd October for repairing my Thomson TV. They quickly responded with Payment details, asking me to pay 450₹ for the Service Technician Cost to create a Service ticket and initiate it.
I immediately paid 450₹ and shared the UPI screenshot payment proof with them (Transaction ID of payment:[protected], which they confirmed that they have received the money.
A week went through, and they never sent any technician, nor took any action.

Finally, on 28th October, they agreed to provide the refund of 450₹ and asked me to share my bank details in which they will process the refund. I immediately reverted back to them with my bank details for them to deposit 450₹ but they never refunded. Everyday, I drop reminder mails to them for the refund, and I call Thomson Customer Care at least 6 times daily, I've reached out to Thomson innumerable times over Phone and E-mail, but they refused to respond neither on Mail nor call, and are not refunding my 450₹. I have all the payment proofs & Email proofs, of ticket raised, payment made, payment confirmed, no action, their promise to refund, my bank account details shared, following which no response from Thomson.

Kindly help me, to receive my refund of 450₹ from them, which they are cheating me of.

Similar to how they are cheating me, they cheat all other customers to, which you can check out on the link below.
