Defective cellphone supp**** by Telkom

On the 18/01/15 I signed a contract with Telkom for a Samsung Galaxy Note 4.Thereafter I was told their is no stock as the batch that came in was defective. I finally received the phone on the 21/02/15 at 16:30pm. I did not use the phone as it needed to be charged. The next day I discovered that the phone was not working, the charged battery ran down without much use and there was no signal. My work requires a lot of travel so I sent my father in on the 24/02/15 he was told that the phone will be sent for repairs and I needed to come in personally. I went to store on the 28/02/15 the store was closed due to load shedding. I then went back on the 8/03/2015 and handed it in. I was informed that the phone will be sent to Samsung for an assessment and in will be getting a new phone in 2 weeks. No one got back to me I made numerous visits to the store with no avail. On the 18 April I went to the store again and the consultant handed me the original phone that has been repaired.I did not accept this and did not take phone, they escalated this to the store manager who has never helped and always on leave. I have paid all money in full and still 6 months later I have no phone. Please help
