Can I buy Bitcoin with Paytm on coinswitch?

I'm considering investing in Bitcoin, but I'm not entirely sure about the process. I've heard of Paytm as a popular payment method in India and coinswitch as a platform for cryptocurrency exchange. My question is, can I actually buy Bitcoin with Paytm on coinswitch? If so, what's the process like? Are there any additional fees or limitations I should be aware of? It would be great to get a clear understanding of the steps involved before I make my first purchase. I'm also interested in knowing if coinswitch offers any customer support in case I run into any issues during the transaction.
