Paid data not loaded

Hi I bought data online using my credit card. I received receipt with ref number that my purchase was successful; but my data was never loaded to my SIM card/account. I always buy my data this way, by logging into my online account. What is very frustrating is that, when I call the customer centre number 081180, I only get self-service options which do not apply to my problem. There is no option to speak to a consultant. I went to the Northgate branch, also they could not help me even though I showed them the receipt on my phone. They only gave me the same number that only have self-service options; or suggested that I go and print the receipt and bring it to them they will then email it to head office and it will take up to 48 hours for them to get a response. They can't give me this email address because it's internal. All this time, money has been taken from my account but I do not have data. I know for sure that the number is correct, because I logged to my online profile that I use every time when I top up my data. How does one get to speak to a person at Telkom?
