Tata Docomo — incoming calls not coming

Hi i am unable to receive incoming calls on my tata docomo number. I have done a recharge of 398rs for 84days. Please have a look my registered number is [protected]. I tried calling your customer care number but unable to reach. This is very disgusting service from a reputed service provider like you. Its been a month i am having this problem and don't know how to resolve it. Please refund my money and i will port my number. One of worst service provider.
