I m a holder of airtel prepaid mobile services from last 6 years. recently I have a problem regarding no outgoing call in UP(West & Uttarakhand). incoming calls were still active but whenever I have tried to call from my mobile, the number could not be connected & disconnected with a beep tone. I have logded complaints to customer care services, but it is deeply regretted that the problem remains same. The request reference nos. are COGCL312023301,COGCL211302014, COGCS31130712. COGCL31128359412. I make frequent visit to UP(West & Uttarakhand). So I have to face such type of problem everytime. I think customer care service is not considering my complaints. Kindly look into the matter, otherwise I m going to change my service provider.My mobile no. is 9936336201
