Trai — general observation in telecom as a retailer

I have observed few problem which needs to be resolve
Wrong recharge: either recharge to wrong number or different domination should be refund even single rupee (Including first recharge any or tariff) its hard eared money
Tariff: tariff should be clear should not be hidden any think means to it should be transparent
Vas service: hardly any person using value added service so its better to activate vas trough recharge or at least one time password (Otp) to activate vas.
Balance deduction: amount should be reserve for talktime only, should not deducted if data pack got empty. Better ask permission to access data over remaining fund. Usually company run trough balance amount once data pack got expire.
