Consumer Redressal

My tata docomo complaint no for the mob no 7411223388 :477803547. I am using Tata Docomo postpaid connection. I am facing mobile network speed problem in 2g data which is running at 2kbps speed from May 8th from when I raised complaint. I was communicating to appellate team but I am not happy with their communication. Apart from solving my problem they are keep telling me that we are given best speed whichever is possible from their end so the best speed will be 2kbps means I am wondering I have sent multiple mails for some clarification but still they are telling they are giving best. If they are giving best speed which is 2 kbps even I can pay the best money of Rs.100 for Rs.799 will they agree with this.
