POOR TO NO SERVICE

THREE MONTHS ago i logged a complaint with Hisense.I was given a credit/exchange authority. To date my tv has not been exchanged.I have been given the run around from them.First i was told to get into contact with Atlas.They responded that they do not supply the store i purchased the tv at.Then i was told the store should handle the complaint,needless to say they are of no help.After emailing Hisense customer care they again referred me to Atlas and has the audacity to state that 'the client is fighting'.My warranty will expire this year and Hisense is still of no help.I have no made contact with the ombudsman to assist.
