Samsung India — washing machine

My register mobile no [protected] / [protected], i have raised complain on 10 sep 18. Engineer was visited on 11 sep 18 and detect problem that pcb was us.
Engineer confirmed from store that pcb also available.
But till that no one bother about it.
I want immediate action. And let me know the reason for delay. G

* my service request no.[protected] dt 10 sep 18 and assigned to engineer mr akash (Mob[protected]) sms by samsung co. From samsung co some one was contacted at appx 830 for visit on that day, that time i was on outside, so ihad tell them tom next day as early as possible. At 1200 hrs on 11 sep 18 samsung engineer mr asit was come and checked the and told that pcb was un serviceable and contacted store and confirmed that parts was available. Same time service centre instructed to mr asit to wait at customer point by the time item should be reached. But mr asit was too busy that he was not wait and just leave the place. After that i was contacted several times but they are attitudes very lethargic. On 12 sep i had contacted to centre at 1145 hrs, thay were told me told me engineer was on the way and will reached by 30 minutes. At 1630 again they have that engineer is just leave the centre to customer for rectification. Now my question is that above the statement given by samsung co. Is digestible by customer? No time value for customer?
