Samsung — washing machine samsung wf 7652/suv/6.5 kg front load fully wm

I, mr. Kersi engineer of 84, lenin sarani, flat c/15, kolkata 700013 made a complaint in april 2020 for repairs to my washing machine which was out of order. Subsequently my complaint number was given ref. [protected]. Since then the local mechanic has called me 3 times (On 07.05.2020 from nos[protected] and on 09.05.2020 from [protected] and also another from [protected]) and confirmed if i still require repairs. I confirmed that i still require them. Later even i called them to ask when they were coming and they said after lockdown is over. I regret to say that till date no one has come for repair or even contacted me since the last 3 weeks. All their numbers are either always engaged or when it rings, no body picks up. I am now fed up. I had told them that my washing machine no power when main switch is switched on. There is no problem with my main switch. No one answers the phone.
Please help. Please reply to me on my mail [protected]@yahoo.com.
Awaiting your kind reply.
