Terrible communication. Appalling credit control.

After requesting that our scheme be transferred from my husband’s name to mine the communication from Fedhealth has been appalling. ...cut a long story short, two years later they are are handing me over to ITC for monies paid to them in 2017. They received the payment allocated it to my account then *****ed it up on their side, apparently refunded the money...however cannot supply proof of payment. After numerous calls, emails, calls, more calls and emails I eventually received a call in 2019 from CHENELLE who has dealt with this case since 2017.... admitted it is their mistake, and that I am now being held to ransom to pay money I do not have for a mistake not made by me. I have since cancelled my membership but I am still being hounded, and cannot get a straight answer from ANYONE at Fedhealth. Pathetic! I have reference numbers coming out my ears! I have requested that I be contacted specifically, however communication is still sent to the wrong email address!!
