I've been ****** and given ******** service

I've purchased airtime using the *120*2272# app, the money got debited but I've received no airtime, I've call the call center and was put on hold for about 15 minutes, I'm very unhappy about this service, if I do not get any feedback I will post more complains, R35 may not seem like a lot of money but it's money that I worked for!!
