Vodafone India — false promises

On saturday 10aug18, i placed online order for prepaid sim and paid money. I received a confirmation that the sim will be delivered on sunday, 11 august. I was tracking the shipment online and was surprised to see that the sim is delivered and activated on 11aug19.in reality i didn't receive the sim nor did anyone called to set an appointment. Suddenly received a sms saying the ecomex couldn't reach me and i need to call them back. I did call them and they promised that the sim will be delivered on 12aug between 8am and 12noon. No calls, no sim till 2pm. So called ecomex and vadofone call center for my disappointment they do could not provide satisfactory answer why the delay is and the person from ecomex suggested that i call vodafone and ask refund. I called vadofone and spoke to ajith and he promised a call back.. It's 6pm on 12aug and i haven't received a call back or sim. What a frustrating and time consuming experience so far.. Extremely disappointed the way vodafone service is provided by poorly trained staff..
