I booked reliance big tv on 14/march/2018, booking id no. Is[protected]Having installation time of 30 to 45 days). But after 60 days my installation not done. I called to customer care no. - [protected], they said to install after 15/june/2018. I am not comfortable with this new date.
If installation is not possible in 1 or 2 days, then refund my pre-booking amount. I do not want to wait any more.
