Transunion outside their own SLA - bad service

I logged a dispute with Transunion on 14 June 2022 regarding a judgement on my profile. I am a paying customer with Transunion for many years now. Today is more than a calendar month later and only now can they tell me that the dispute will have to be relogged. I was told many weeks ago that this won't be necessary even though I logged the dispute under the wrong category - I was even told that this will only cause the turnaround time to be longer i.e. 20 working days instead of 7. This is after I've phoned them multiple times to follow up on my dispute. I've been promised multiple callbacks which never happened.

The level of service towards a paying customer has been absolutely shocking.
