Sargam Electronics — unprofessional behavior

Address:

New Delhi, Delhi, 110059

Date of purchase - 7th of may
Invoice no - gst - sun - 879
I have purchased one lg 6.2 kg fully automatic wash machine and till then i am following up for the demo service and every day i am calling there but the same response they are giving me that by tomorrow they will send the executive from lg. Also when i received a call from lg executive, he said that only till 5:30 he can come for the service. However, at the time of purchase sargam electronics has promised me for this service till 8 pm.
Also when i have asked them to deliver the product after 7pm at my place they have sent that product at 1:30 pm noontime on next day and nobody was there to receive the product. I had to ask my neighbour to receive the same.

Is this the service you guys are providing to the customers??
