Please explain process of Cheaquebook application process for PNB

Please send chekbook applications for Punjab National Bank. My cheaque book is completely used and I need new check book. How and where I can get new one . What is process to get new cheque book without visiting bank because now a days there are long queues in banks and they are only dealing with cash withdrawal and deposit. I am worried because check book is very necessary for my work and if I can't make payment in time , I will suffer big losses. Before this all my transactions were using cash so there was no need for cheaque book but now after currency ban, I need it desperately but banks are full and I can't even get inside bank to apply for it. So I need process to get it without visiting the bank.
