Technical problem on the phone and no one wants to take responsibility between telkom and insurance

I'm so disappointed and devastated at the same time I bought VIVO 17S in August it gave me problems I sent it back to telkom and they sent it to the insurance,,, the insurance never responded until I went to telkom store after a month and telkom communicated with the Insurance , the insurance response was, telkom shouldn't be sending this issue to them its still within the warranty period since that day I have never had a straight response answer, the insurance said they will send the phone back to telkom because the issue seem to be the technical problem,.. It will be sent within 4 days, I went to telkom after about 7 to 10 days because I haven't had anything from telkom, when I got there I asked them about my phone they went and look at thier store from come back with nothing, I asked them to check on the system because it suppose to be the2at their wear houses,, they did that the phone was there and thy went back to Che properly they found the package but when they opened it, it was a deferent phone deferent brand 😭😭😭😭 ever since that day I have tried to communicate with the manager he never had a positive answers I have been waiting and waiting it really frustrating I don't have a phone to use and my business has been comprised the whole December I'm just waiting I don't even know what am I waiting for... I have been paying their installments including the insurance I really need help please
