I have paid all my amount and now they are not giving any answer. I want my noc letter. Its all started as below.
They call me on my phone number and tell that this is your pending loan so you have to pay your remaining amount and you will get your noc letter. I have cleared it and now they are not giving any response 2-3 days they gives me excuse and now they are not picking up my call. I want my noc letter
