You need to deposit 250 for gold account and need to make at least 30k PA or 3k earmarked in bank a/c to open a platinum account.
Platinum account can be opened online but gold account needs to be opened either at the branches or d/l the form print it out and mailed.
Withdrawals for gold accounts still need to physically go down to outlet to collect while for platinum can be done thru bank transfer.
It's obvious they don't really want to waste too much resources for online processing. Also you need to call in when making football bets even if you have an online account. Something to do with preventing ppl from placing bets that would favor them during live betting.
