Empty Promise

I received an email from Nedbank stating that my credit card limit had been reviewed and I was eligible for a new (higher) limit. I checked with my branch to make sure the email was genuine and on confirmation that it was I signed and returned the form. Two days later i get an sms declaring that my account has been reviewed and my limit revised to the same as it currently is!! Either its two departments that do not have a clue what the other is doing, or its an empty promise to make me feel good about myself and them but then they let me down by retracting their statement. If it was not such a hassle to move my four personal accounts and company account I'd move the whole lot to another bank!
