ABSA bank no service!

I've been a member of ABSA for many years, their service is absolutely disgusting. I've been offered a credit card increase and received a msg that I need more documentation (2 months ago) immediately ive sent required documentation, yet I received another sms my documentation is required so I went to my nearest branch and sent the required documentation, again I received a msg that my documentation is required and this is after I received emails that ABSA did receive my documentation. I have phoned ABSA several times where they promised to get back to me within 48hrs and then I need to phone because I don't get any phone calls. So today after struggling 2months I went to FNB, they helped me within 10min where ABSA failed to help me within 2months. Thanks ABSA I'll move all my accounts to FNB ???
