Tata Docomo — HOPELESS service

Hi there, I'm Abin On 14th of August some Customer care executive called me with a plan to change my prepaid to postpaid connection. And I was happy with that plan. On that day itself one guy came and collected my documents along with 300 RS(Nemesis Solutions). And he said it will be activated in 48 hours. On sunday someone asked me to sent a message to 121 and I got a message with RID[protected] from Docomo. Today I called 121 and asked about the status. He said they need 72 hours more to change this prepaid connection to postpaid connection and he said to call [protected]. When I called on that number he asked me to call another number [protected]. Now I'm feed up with this. Your Customer care service is absolutely HOPELESS. You guys called me a several times to take the connection. Now there is no any response from any one. Now I'm planing to go with number portability and change the service provider. So I need my money back. Please don't tell me to go somewhere and collect the money. And please do the necessary things.
