HOW TO : scrap a website with simple search buttn, nd pagination

Hello Experts,

I am calling out for help here as I am a newbie to scrapping and roughly 1 day old user of Web scraper. I have gone through many videos and how to guide but I am not able to scrap a simple website of allahabad bank where I want to download the branch wise name, ,IFSC ,address, Cde ad phone number and email( Email is compulsory out of all elements . I am failing badly hence it could be small basic issue or a blunder both.

Can you all please have a look at error below and suggest if it is some issue or its a bank website hence this information is being rejected by server monitoring bank pages.

Further, If possible someone can either record the scrapping and send me the sitemap, it will be great. Basically once you will get into this website link given below, you click "Search" , a list of 12 branches will come on screen . Same can be further paginated using the next sort of page number link but I am seriously about to bang out my head as I have attempted the same scrapping for almost 100 times but now I dont have it any more in me. So guys please please bail me out.
