Experian poor poor poor service

Firstly i had to dispute a Nimble account on my profile, I sent an email through to experian to assist. A couple of days later they called me to let me know they would investigate the matter. I subsequently app**** for vehicle finance which cannot proceed unit the dispute is closed. I called them on Friday the 10th December 2021 to cancel the dispute as it is effecting my finance application. They canceled the dispute and let me know it would take 48 hour to update on my profile. I called this morning and they let me know that the dispute was not closed because they received feedback from Nimble so everything they needed to finalize the dispute was in order and they would email me the confirmation. I called again in the afternoon (waiting around 40min per call) wanting my confirmation email. The lady i chatted with told me the dispute is still open and they have 11 days to email me. I simply cannot believe that a company would blatantly lie to their customers. All conversations are recorded and yet they dont care. I have also sent though numerous email and no reply.
