Very frustrated and angry client

Friday 29/06 app**** for a MacBook contract at Telkom (Adderley street Cpt) and told I would receive my device on the 03/07 and would be contacted. With no contact being made, I contacted services provider and told I would receive device on 05/07 again no contact was made, I then went back to the store and then I would receive my device on the 12/07 but the assistant hadn't even asked for my details to confirm this. I fail to understand when the customer ever wins or even considered. Very very very bad service Telkom from a very frustrated and angry client.
