Rancid meat Checkers Willowbridge

On Saturday 27 March 2021 i bought an matured Angus fillet from Checkers Willowbridge On arrival and on opening the vacuum packaging the meat was rancid. On returning the meat for a refund the manager in full view of other customers proceeded to discipline/chastise the Butchery manager. She also told me she has had numerous problems with the butchery. Very unprofessional behaviour . Not a pleasant experience . This meat wasnt just off it was 'vrot' Very bad customer care!
