Irresponsible and Incompetant staff

I upgraded my cellphone contract on a Sunday 15 Feb with a Sumsung galaxy A3. On Tuesday 17th Feb I took the cellphone and its accessories back to vodacom as the battery was not lasting a day. It was taken in as an OBF and I was promised to get feedback within 7 days. On the Thurs 26th Feb i visited the vodacom store enquiring about the phone, and I was promised feedback on Friday the 27th. It is now Sat the 28th and I have not received any call. I called the store and Charmaine is on leave, spoke to Yugen and his response was it is not his department. But he said to me that the accessories for my phone only went to the repair centre on Friday 27th. My frustration lies in the incompetance of the staff, surely all the accessories should accompany the phone. Dont pass the buck and after me complaining dont tell me that the store is busy. My complaint should be be dealt with efficiently as i have been paying for a phone that i dont have.
