I reached to that part of the tutorial where it is required to create a digital ocean account. There was a promotional link attached, on clicking upon it showed that it is a 50$ credit for one month but as soon as i entered my bank details and saved, it debited 372rs from my debit card. Please help in this regard.
The money should be refunded in few days time. If you don’t get a refund in 7 days time then write an email to firstname.lastname@example.org
