Experian won’t remove incorrect info

Wow after XDS, Transunion and Kudough fixed the info on my credit profile. It’s taking Experian weeks for them to respond to their emails and an agent called Gareth Leibrandt is not reading the emails and asking me stuff that’s already on the mail and he responds after weeks! Wow I’m so annoyed at the lack of customer service and judging by all the reviews, Experian thrives in providing extremely bad service.
