Reliance Digital — AC delivery not done

I bought an ac from reliance digital offline store. They said it will get delivered by 4th of may and be installed by 5th of may. None of these happened.After Numerous calls and hardships on 8th may i got a sms saying that the product will get delivered by that day but that did not happen either. On 9th may morning i got a sms saying that product failed to deliver due to invalid OTP. But no delivery person showed up and NO OTP was given. What a rubbish situation to be in. There is no number of the delivery guy also. Just the RTO number of the vehicle is there. I dont know if i will get the product. Well it looks not.
