Worst service ever

I would just like to say that i am very disappointed in this company for not following up on their duties. On the 18 March 2020 i sent an email requesting a dispute off my clear score for Home Choice. First i requested a paid up letter from home choice and received it than i sent an email to Emperian SA requesting for them to take it off my clear score because its giving me a bad credit record whereas this account has been paid up. They did respond to my email saying thank you for my request the dispute will take about 20 working days to be investigated. The person who emailed me was Reneiloa. It is 8 months later and still i am being charged for an account that has been paid up but shows outstanding on my credit score. Yes i know it has been Covid-19 but i mean they told me 20 working days and they still never came back to me regarding the hold up or anything what so ever.
