Appalled!!!!

I bought a phone at pick n pay hazel dean Pretoria and recharged with a total of 29 and was suppose to get R100 airtime and 200mg data after my first successful recharge of R12 which I made. I have contacted vodacom at least 5 times about my airtime and each time I get the run a rounds. Tonight I spoke to a rude girl Olga Mtungu who honestly does not deserve to be employed by vodacom or any other company for that matter because her service was appealing!!! She hung up on me and refused to help. Requests have been logged by your Rep, manager and agents and nothing resolved. My number is+27 64 ********** can someone fix this issue please.
