Threatening to close my account for no reason!

1stly, I pay monthly fees for a Relationship Banking services from Nedbank and yet I receive no such services, I do not know who my banker is, and I'm basically treated like any other banker even though I pay higher fees.<br> Saturday, I received an sms stating as 'per previous communication', the account will be closed, I have never received any communication about the account being closed, and if the account was to be closed, it would be because of a negative balance which is less than R700, and I can pay that off anytime. After this bad customer service, or lack thereof, this is what Nedbank decides to do, I think I might want to them a favour after this month end and my salary has been paid, and move on and leave them. I tried to call the number but could not ngo through several times. This is ridiculous!!!
