[Resolved]  Airtel — awaiting assistance at the earliest

Earlier I had an old model airtel4g sim(with no adapters-standard size) which I wanted to swap with a new one(with adapters for micro and nano slot), since my phone demanded that. So I went to this retailer and bought the sim for 50 rupees. I was instructed to send an SMS stating "SIM sim number" to 121 through my earlier sim.I got a message which read "reply with 1 to confirm".I did the same and got a reply message stating that the sim card would be activated within 24 hours. I waited for the time being and my earlier SIM was out of network, so I swapped the new sim but it received no signal. I contacted the customer care and they informed that I will have to wait another 4 hours for activation. Again I waited for the time being and after another 20 hours my new sim was out of signal. This time the Customer care instructed me to visit a nearby Airtel store. I did the same. The guy there asked me to show the request message I sent to 121.After seeing the message the guy said that I have messaged the wrong sim no. I messaged the number on the cover in which the sim would come. The guy at the Airtel store obviously didn't believe it, but however he carried out some standard procedures which includes getting my Aadhar number and thumb print and said that the new sim would be activated in 4 hours. He charged 25 rupees for this. Shortly I received a message through the new sim stating "your number is xxxxxxxxxx.Please restart your device". I received a configuration message which I saved. My happiness was short-lived. Suddenly after I chose to save the network settings my new sim was out of signal. It has been 20 hours since then no signal reception yet.I have restarted my phone several times but in vain. Now I know why the newcomers excel in the industry it's because of their service. Worst customer service. All my contacts know only this number which has no signal. I regret buying the new sim. Better not buy thus sim again.
