Disgusting service and bridge of contract.

On the 22nd May 2020 we upgraded our contract *** at Vodacom Shop at The Mafikeng Mall in Mahikeng. Oupa, who was the available consultant helped us. We decided on the new Samsung s20 on a top up M package for just over R1000. 00. Two days after receiving the phone we experienced problems with it. It kept on restarting itself. We returned the phone and one of the other consultants told us that it was one of the phones settings which caused that and she switched it off. We went home but later that night we experienced the same problem. We noticed the next morning that the phone also did not charge even though it was plugged in over night. We returned the phone within 7 days and another consultant Tercia booked the phone in for repairs under "out of box failure". We waited almost 3 weeks for feedback but no one called us. I decided to call myself and I was told that the phone was at the other branch in Megacity Mall. When I called them a gentleman helped me and told me that the phone was rejected and it's on its way to Mafikeng Mall branch. I called Oupa and explained to him and he said that he would call me when the phone is at the store. After failing to call me throughout the weekend I went back to the store and Kea assisted me. She called the other branch in Megacity and she was told that the phone is still there and that they would sent it to her. After a few days she finally received the phone and called me to collect. I went there today for collection but when me and Kea opened the box the charging cable was not there. She advised me not to take the phone as they need to escalate this matter back to the repair center. We already signed this contract a month ago and up till today, the 25th of June 2020 we have not yet received a phone. The Vodacom contract clearly states that phones with out of box failures within 7 days would be replaced but we are now being treated as if this was our fault. With all the promises made by Samsung and Vodacom I really feel like we are being cheated. We had this contract with Vodacom for many years now and promiss that this would be the last time I ever use Vodacom. I am truly disgusted by the service and We are going to seek legal advice.
