Reliance Data Card — worst service

i am sumit kumar sahu having data card no [protected] is very slow and
i have gone to the service center and they gave me the solution and i
am sending the attach file of the job-sheet. If i am giving the data
card to the asp then they are taking more than 15days to give us the
service which is very late. When i complained on this matter you have
not taken any action. When i am contacting to your customer service
then they are not giving me the proper solution and they misbehaved me
4 time till now. When i am telling to give the solution they are
writing a complane and telling me two wait for two days. Like this i
have waited for 5 months but till now i have not used the internet. So
i want my money return. I am asking a question that why are they creating these
bustard things if you have no solution. when your engieneer called me
on phone to guide i also helped him but it also not worked and i told
me that the web page is not opening. They told me that we will call
you with in one day for this solution but they not called me for 3days
and not till now. If you want anything else then contact me on my
phone no [protected] as soon as possible.
