Unable to contact Credit card call centre

I have been unable to get through to the Absa credit card division for about 1 week.<br> I have spent about 3 frustrating hrs listing to music, without a single response or call back service. <br> Appalled at the lack service, even after raising this concern with the general enquiries section. The Manager was also not able available to take my call, and I have not received a call back since.
