Rochester

Returned a faulty couch within the guarantee period. It was collected and supposedly fixed. I noticed screeching noises In the couch which was never there and was told I had to payfir it to be fixed..The initial fault was just a bracket that had to be fixed.in the interim I experienced further problems with this set on another recliner which I reported still in the guarantee period to this date it was not collected neither have I received a call from Rochester. Went into the store spoke to the assistant manager and she agreed that the couches had to be fixed. After so many calls I eventually spoke to the manager who was not of much help. To date I have not received the 2 seater couch or a call this is almost 4 months later.i was thinking of returning the couches that I still have. I have stopped my payment for Nov. But Dec has gone off my account. Worst service ever from any store that I have experience. Can someone please advise a way forward
