delete account

Hi there! Somehow I opened two accounts but I can open anyone! Therefore I try to delete my account to be able to open a new one to be able to use discord, but....... The explanation how to do it is ......, not really useful and it would be helpful to receive an explanation which will be useful or you delete my accounts associated with Darko Genc or my phone number 385922878053 and let me know. Thank you!
