Dear sir / madam i am using airtel bearing no. [protected] since 2012 since then i facing indoor coverage and no optimum speed provided by airtel. I have written several mails on the issue with applet and nodal officer and several voice complaints but so far no services been given. I requested airtel to install booster at my location with providing electricity charges for the boosters. But last seven years they are denying the job and not providing the support. I am paying my bills before the due date.
