Cell C do not care about clients.

Upgraded my line 0n 28 October. Received Laptop on 29 October. Laptop faulty so I logged a call for collection to replace. It is now 24 November and Laptop still not collected. Collection was cancelled 5 times already and no one at Cell C knows why. Spoken to 2 managers that promised to phone me back, But as to date no manager has phoned me back. I am so frustrated and think that as a loyal client with 5 contracts at Cell C for over 10 years that at least they will treat me better.
