Bad service

I am very dissapointed I have purchased airtime for the amount of R30 and again for the amount of R5 the airtime did not get through to my number but I got notification that the airtime amounts were deducted I never received any notification from Mtn saying airtime was loaded so it means Absa is the problem what if I needed the airtime for emergency and they tell me I have to wait two to three days I mean what is that this is my airtime and I want to use it that is why I bought it today
