Disappointed Client

I have a business account with FNB, it was handed over due to not been active. I paid the amount due to the debt collector and requested them to reinstate the account. I call FBN business banking and waited for about 15 minutes to be connected to the agent on the 16/04, I requested for my account to be re instated, he promised me that I will get an email from admin@fnb and I should just send the POP and the settlement letter received from the debt collector, I am still waiting for the email, the agent refused to give the email so that I can send the required doc. It is so sad to be treated like this from the bank I have been banking with for over 20years.
