Uuurrghhhh!! Vodacom is the worst!!

I have bought airtime and get SMS saying recharge with so much and we will give you bonus airtime. I recharged and did't't get my airtime. I called and lost all my own airtime. I called to complain and said I should call back the same day as they can't pick it up the next day!! What bull **** it that!! They have a recorded of everything you do. So today same thing and no airtime. So I call in the same day and the agent keeps me on hold for 10mins just to tell me but I got the same SMS saying that I would get the airtime. Gosh women don't you listen to your clients. I said I got the SMS but not the airtime. So he says hold on again!! Another 5mjnd holding on to tell me I do have the airtime already. So she drops the call and I check. No airtime. The time you respond to this complaint it's too late to check!! Why is your service to bad!! Why!! Doesn't it matter to you! Why do you treat Clients like this!!
