Missing Airtime

Hi,On Saturday 25th July '15 I purchased a sim card @PEP stores in westgate.It was RICA and everything.When I got home I obviously activated the sim and I was sent a Cell number : ***.I purchased R55 airtime which successfully went through.I then wanted to buy DATA and to my surprise it tells me I don't have sufficient credit to buy DATA.I then called Vodacom call centre spoke to Yolanda Njenjele who placed me on hold for tehnically most of the call.And all she could say was she's checking something.When she eventually returned she could not even give me a proper explanation as to what is happening.I was rather asked whether I had a contract before,I never had a contract with any cellphone network.I was eventually told that the sim card that I purchased does not exist and that I have to go back to PEP so they can sort it out.I aksed about my airtime and was told PEP has to sort that out aswell.How in the hell do you send a customer back.That is pathetic.I was placed on hold again and was greeted by Donovan Abrahams (a \team leader")."""
