Getmecab — Fraud, theft and duping of money

Hello,
I had booked a cab from this service provider from 14/10/2021 to 19/10/2021 from delhi to khajjiar including various stops. Total payment to be made was 21000. Cab provided by them was of inferior quality. Driver was also not well behaved.
At the start of journey, driver asked us for half of the total payment. He was paid 8000 on paytm and patrol for rs 2100 was also filled by us. Along with this he also asked us for recharge of 500 in fastag. Whatch was also made.
On return from khajjiar we planned to stay at Ludhiyana. However at khajjiar on 18/10/21 driver asked us for complete payment which was made to him after confirmation from the company.
On reaching Ludhiyana, we stayed at our friends place. However, driver asked us to leave at night for delhi. Which we refused because we were already very tired. He left us at Ludhiyana itself and ran away with our stuff. On contacting the cab service, they told us they they will arrange another cab but we will have to pay for the service. We paid 4000 for the new cab. They assured us that they will refund us the difference in 4 days.
Now more than 10 days have lapsed and they have not even made any efforts for initiating the refund. They are asking me to contact the driver whose phone is switched off.

This has led to mental torture, and harrassment for me.

I demand to sue this cab service for theft, cheating, duping me of money, making false promises, harrassment, disturbing my mental state, causing discomfort to me and my family members, leaving us stranded at Ludhiyana without any intimation and charging us extra money.
Please help.
