Disastrous Customer Service

I ordered two Tablets via Vodacom Online (Sim, Connection and Delivery charges are waived when ordered online). The delivered the tablets on Wed(20 Jan 2016). Took the devices to Customer Care(22 Jan 2016) and both tablets faulty. Arranged for Vodacom on 23 Jan 2016 to pick up. By Wed 27 had not received any response.<br> Account had been debited with Connection included :( Raised the issue with the CEO's office. They responded via email that A CREDIT NOTE will be issued after erroneously taking money from my account and they will advise of the tablets. Today is the 29th of January and I have not had any feedback regarding the tablets. I am still sitting with two faulty tablets. Where has service gone in this country that not even a CEO's office cares about the customer. People please consider when contracting yourself to companies like this.
