Worst customer service ever!!!!!

I took a Samsung cellphone July/ 2024. The phone has been giving me an error message since February. The account is update to date but the error message states that i am owing. The error message prevents me from using the cellphone yet im paying for it every month. I called call centre so many times and they said old me they only help with accounts… I have taken it taken it to multiple Vodacom stores and the took it repairs… It had been taken to advance repairs in polokwane and another one in gauteng and they say they cant fix it. I was advised to call after sales so they can replace the phone but they keep giving me runaround. The two ladies that i spoke to at the after sales call centre didnt care to listen to what is really happening… They said i should take it back to vodacom again and i did and same story all over again. No help. The service that i have been receiving is absurd. One would swear the phone was given by to me for free. The phone is not even a year and my contract no ***. Recent job no ***1 with vodacom Lephalale mall. Please replace the phone since no one at Vodacom can fix it. Or else cancel your contract but i wont owe you anything at all. I cant pay for a phone that is not working.
