Changed for devices I did not receive.

Logged a review last week Wednesday, 05 February, regarding being changed for handsets I never received. I phoned Vodacom still on Wednesday the 5th and I was promised a call back from the escalations department to be updated on the status of the query. I received a call on Saturday the 8th and the was some sort of progress. I was the given a name Ayanda Khumalo who was supposed to call me to update me Monday the 10th and still no call. Phoned back today the 11th and was transferred from one consultant to the other and eventually given non existent numbers to follow up and sadly still no resolution and still no call from Ayanda Khumalo. I am beyond frustration, promises are not kept and the charges are still on the bill. My advise do not take any contract with Vodacom, horrible customer service you will experience, lack of feedback and no care for their customer.
