HCL Technologies — Voltas Beko Dishwasher

Hi, I have purchased a Voltas Beko dishwasher from Reliance Digital and raised a complaint on sound that's happening when we ON the machine. Executive (Mr.Sunil) visited and he said he has replace the Belt and got vanished by cancelling the complaint. Now, he is not attending and if we call the customer care they keep on hold and disconnect the call. Now, as i have been under Resq plan Voltas customer care are not taking up this complaint and now the warranty is also going to expire
My request to all NOT take Resq service as few of them are very un-professional
