Veolia — Unprofessional staff

I would like to bring to the notice of Airtel networking system Manager.

My mobile No:[protected] which I am holding since 2000, of late has been tampered by Airtel staff and quiet often they deactivate my out going facility. Despite several letters and request convincing them that it is a corporate number they do not understand and it is to no avail. I am a guy with cardiac difficulty, unlike a pacemaker a mobile is a handy for a guy who is making SOS.
Therefore as a staff of Veolia I request Airtel top brass to look into my issue as early as possible. Revamp uncouth unprofessional staffs train them if you find inadequacy in them to realise the value a customer. W Regards Manasseh Joseph
