Due to no proper Response and delay in Installation I have cancelled the Excitel Connection by calling their Customer care Number[protected]
And they told They will Refund the Security deposit( INR 2000) and Excitel Plan( INR 590 ) but I got only INR 2000 only and INR 590 is been pending for last 15 days..
Am keep on calling to their Customer care people. But not Resolving the issue and prolonging by telling that Payment team will contact me.. But till now no one is calling and resolving the issue
