Trying to buy data from Telkom - Website is useless

Good day

I have been trying to purchase data for my dads adsl. I have logged into Telkom and it does not let me in, keeps telling me my username or password is wrong. Then when I try to change the password it still tells me it wrong. I called the call center who told me to call the sales, I then called the sales and they told me to call another number which I did. I then call the new number 10210 and they told me to call sales again. This is now becoming very frustrating. Who does one by data. Telkom have changed their website. If you do get in there is no where on the page to purchase data. I am a very irritated customer
