sales rep of beam a bit relaxed in their attitude they just want to get new customer but dont bother about deadlines for instance if my case the rep promised the installation will be done in 2 days but it was not done and I had to make a lot of calls and the rep most of the time did not bother to pickup the phone, finally I had to call up my friend who knew some people in beam and there after 2 days my installation was done, so I guess if they say installation will be done in the 2-3 days expect a week, Just felt that Airtel team is a lot more professional and beam on the other hand a bit lax.
hee hee thanks for those precious information
i wanna give beam a short really sick of Airtel now
