Claim declined due to insurance cancelled without my consent

I am highly disappointed in the service I have received from TFG staff. I have submitted a claim on Monday 28th October, then after numerous follow ups, learnt on Tuesday 3rd Dec, that my claim was declined because I cancelled the insurance on the phone in question. I have clear evidence of emails sent to customer service, requesting cancellations of 2x vodafones (not the phone for which the claim was submitted), clearly provided the product info on the cancellation forms. With my first request, I received no response. My second follow up request (2 weeks later), I was advised that my query was escalated, and then again no response. Until I learnt that they went and cancelled insurance on the wrong phone. I was assisted by Walter at Finrite who reactivated the insurance and deactivated the one which should have been deactivated, but they were not able to assist with the claim since this was TFG's error. I have already waited one month (with no feedback), now I have to wait for TFG to investigate and provide further feedback. I submitted my claim a month ago, whatever errors happened internally, is not my problem. I need this resolved asap, I cannot wait another day, week or month. My account is up to date at all times, but now I have to be the one waiting. I have to return a borrowed phone to its owner. Please assist ASAP.
