Airtel Retailer — Sim card rejected

Address:	Coimbatore, Tamil Nadu
Website:	Airtel.in

My number is [protected] and this number was used by me from 2004 till date and I had no issues with airtel and i love using this network cos of the best reach among the nation.I was suprised when recently a dsaster blew my hopes for airtel.I bought a new mobile which as 4G as you know my sim card is very old and needs to be updated so I went to the retailer in coimbatore near my office and for my suprise he said that the sim does not exist and he also asked me to wait for 3 months and he shouted back at me telling me to contact 121.He threw my application and also refunded Rs.30 which he got for activating.I still want to use airtel cos of few people the name is spoilt but the number was with me for 10 years and I have all my contact details and my clients call to that number.Kindly give me a suggestion.Call me at [protected]
