Still waiting on voucher

Hi,my wife and I opened an account at Game Cape Gate in March,we recieved a voucher of R300 which we could redeem when we buy something of R4000 or more,which we did.We were then told that we would recieve an additional voucher of R100,which will be posted to us. We waited a month,and went back to say that we haven't recieved the voucher yet,the lady at the account department told us that we will only recieve the voucher after 3 months,which is ok,but why not tell us this when we opened the account?But anyway,we waited and after 3 months,still nothing,I went back to Game,spoke to the same lady,she tells me that they wer offline,and can't make outgoing phonecalls,i fwe could come back the next day,which I told her I wont,I am not willing to drive up and down for there mistakes!!They have to phone me,that was 2 weeks ago,I am STILL waiting for her to contact me!I would like answers,you are quick to send me the bill on what I owe you,but cant send the voucher!!!!
