[Resolved]  Reliance Digital — ac service is not provided

I have purchased and ac where i was given 3 years of free service. However, after complaining from march till date. No one has approached to do the ac service (Gas refilling). We have been just calling again and again. This type of # service been provided to the customer. If you see the temperature outside is 42 and without ac how would some one stay. I done 100 calls where i was assured that someone would visit today but no one approached. What is this? I need an answer...
