Warranty Repair for 3 months while i'm without a phone

I lost my phone (iphone 8) in July and submitted a claim and a new phone was supp**** to me in August. I used the phone for about 3 weeks after which it stopped charging.

The phone was collected from me as a warranty repair and was with the insurance company (Pinnicle) until early September. The phone was returned to me and after about 2 weeks it stopped charging again.

THe phone was collected from me for a second round of repairs and was with the insurance company all of October into November. Last week i received the phone after several phone calls demanding feedback about my phone. I used the phone over night and the next day it stopped charging for the 3rd time.

When i contacted MTN Insurance i was met with several agents telling me they are new administrators and they cannot help me. All they can do is take down my email and forward it to Pinnacle as this is their issue and the new administrators do not have record of my warranty claim history.

For the last week i have been sent from pillar to post with the new administrators advising they cannot assist as this is a Pinnacle issue. I have been dealing with Nicole Braga from Pinnicle who has taken to to not answering my emails.

Initially when i advised her about the phone no longer charging for the 3rd time i was advised the matter is being escalated with the istore and my phone was collected. When i follow up on the status of the claim i am now being told the phone is being repaired which will take up another month. When i ask what the outcome of the escalation with the istore i was once again ignored. I have requested on email on 3 occassions to be provided with the MTN complaints procedures and i have point blank been ignored once again.

I have been paying for 3 months for a phone i do not have access to use. MTN has supp**** me with a defective phone which they have repeatedly failed to repair. Instead of being supp**** with a new phone i am expected to wait while MTN does ineffective repairs to a device that is clearly defective.

on top of it all, MTN is avoiding responsibility and i am now left to deal with faceless administrators who are busy pointing fingers at each other while no one bothers to resolve this issue.
