Account ignorance

From June 2020 I have been sending emails, made calls to rectify my account, we have been working from home since March 2020, my account was settled 2019. I purchased a coffee machine 2018 for my director's retirement at Brooklyn (2018, account was settled in full??) I queried the interest with a highlighted account for the bookkeepers to follow up easily still - but it's still going on Sad thing is we have not been in Hatfield/Brooklyn area since hard lock down...no one could give an explanation or rectify my account...all emails was just followed by a reference number with no feedback. I am highly disappointed, been a customer for over 26 years!!!
