Accounts not valid

I opened an easy account yesterday through some ladies doing door to door for fnb. They explained everything and told me I don't have to go to the branch. I was told the account number will be provided within the next 24hours and when I received the sms today it only showed four digits as the account number. Worse part I'm told to go to the branch with my proof of residence which at first I opened the account not wanting to go to any fnb branch. I'm writing on hello Peter to let people aware of such inconveniences fnb and it's door to door employees cause.
