Complaint Not Resolved

On the 11th of October 2024, my vehicle went in for its 105 000kms service. It was discovered that my coolant tank is leaking & needs replacement. I was under the impression that my extended warranty was with Innovation, I only found out of the day that it is with Budget Insurance instead, something that was never communicated to me. I called Budget Insurance on the day & the claim process began. The dealership sent all that was required to Budget Insurance on the same day. On the morning of 19th of October 2024, Saturday, I was called by Budget Insurance to inform me that my claim has been disapproved & that an email will be sent stating reasons which was sent on the same day. On the Monday of the 21st I read the email & I had a complaint stating my reasons. I then received a generic response that a consultant will be in touch within 1 working day...that never happened. The only call I received was to rate the call I had received on Saturday the 19th. On the 23rd, I received an email from a Tania Van Zyl from TIH acknowledging my complaint. On the 27th, I received another email that the turnaround time for my complaint is 15 working days from the day the complaint was sent. 15 days have passed & no communication whatsoever has happened. The quotation received from the dealership has subsequently expired. Also (my) time has been wasted due to the waiting as I could've probably made plans to fix the problem.
