bad service on cellphone banking

I bought a phone at edgars 2 years back but I keep on getting sms's for Mr Hendricks who is a client to absa I went to the khayelitsha branch they said they can't do anything to help or solve that again last month I went there because every morning I get sms's from Absa and Roseline Mbele told me ther is nothing they can do because client is not available and that they can't go into clients account without a client being available .what about me that is being iretated by someone elses messages its not nice at all .because I am not MR hendricks and I think they suppose to remove my number from their system coz clearly their client has changed his number and there is no way that their client is also getting messages its impossible and the khayelitsha branch is showing no willingenss to help on this matter .Absa has so do something I'm tired of this abuse
