pathetic service

false advertising, i received a sms saying dial *123# to purchase bundles as my minutes had run. i did so and purchased 100 min. nowhere did it state voda to voda only further to this how do you know if you are calling a voda number?. i called in and the consultant did not understand at all and hung up. i called last week to complain of poor network and was told its known problem however they will log it, to date no reference number or anything
