I have an ongoing complaint which started in July 2020. covered by their tracking numbers A00015246767 - [protected]. I owed a balance of £308.77 which I paid on July 21st by bank transfer, they claimed not to have received. I received a further demand on August 25th and again paid £320 again by bank transfer. They appear to have received July payment but not yet acknowledged by them, they will not return the August payment. They do not respond to and e mails or to the manager of their Castleford branch who took up my complaint on 25th August by their internal mail system, which brought the result of the above tracking numbers. I have sent 2 e mails to their proofs department, but am not getting any response. maybe you can get some response.
