Reliance Digital — TV installation is pending from 2 days

Address:

GK Royal Hills, Ravet 412101

I have ordered the TV on 13th July 2020, on the website it shows delivery on next day, before ordering online from Reliance Digital site, I have checked delivery will be on next day or not as lockdown will be starting from 14th July 2020, I got assurance from customer care that my order will deliver on 14th July. So I placed the order and paid the full amount. But on 14th July I did not receive my order. So I called customer care they took my complaint and forwarded it to the respected team and said the team will contact you.
But did not received any call from the respected team.
I have written several emails also called customer care several times but did not work. On 18th I got call from customer care, they told me that due to lockdown your order will be delivered to you on 25th July, I said Ok and requested them to do the installation of TV on the same day of delivery.
But, suddenly on 21st July, I got my order. But installation did not happen on the same day. I said ok, it will happen on the next day, I will wait.
I waited on 22nd July no one came for installation, as per policy after delivery within 1-2 days installation will happen. But now its 3rd day after delivery no one communicated with me regarding installation. I have called customer care regarding the same, but the same they have taken my complaint any forward to the respected team. And even the executive disconnected my call 3-4 times without resolving my problem.
Reliance digital customer care is pathetic, they did not care about their customers.
Please help me in this.
