Samsung — Rude behaviour and after complaining no action taken

My washing machine was sent for repair to the workshop after changing some parts at home cause the machine was not working even after change of part .On complaning the case was forwarded to their Headoffice and the Headoffice person was suppose to call the next day .He did call on 29 August 2024 and said will look into the matter and get back to you tomorrow I.e.30.8.24. Received a call today afternoon but was missed by me as I was in a meeting .called service centre and they said will get a call in an hour .After 3 hours I called again as received no call and requested them to sent my washing machine back .no response .It is such a big company and they are just jarring the customers by changing parts after parts as we have no knowledge wht is wrong with the machine .Ever time they send a different engineer and each engineer says a new part is faulty .three engineers had visited for my machine and 3 had different solution and. Each changed three different parts .Please look into the matter and resolve it .My machine first complain was main on 10.8.24
