Experian disputes take more than 2 months.

I've submitted a dispute on 20 March 2025 with all relevant documentation. Ive received a reference number only on 14 April. Now they tell me that the 20 day dispute process only starts from when the ticket is created. So it basically takes 1 full month after submitting documentation PLUS and additional 20 business days to resolve a dispute. That is over 2 months. This surely can't be that slow? I did the same process with Transunion and the dispute was finalized within 1 week. So 1 week with Transunion compared to 2 months with Experian. This is ridiculous and I need my dispute finalized TODAY!
