How to buy data from GTBank?

I'm curious to understand the process of purchasing data from GTBank, as I've heard it's a reputable source for financial and transactional data. Could you elaborate on the steps involved? Do I need to register an account with GTBank specifically for data access? Are there any fees associated with the purchase? Additionally, how do I ensure the data I'm purchasing is accurate and up-to-date? Lastly, are there any limitations or restrictions on the type of data I can buy from GTBank? Your insights would be invaluable in helping me navigate this process.
