Poor service

On Friday I had a problem with telkom. I bought data for R55 and that data didn't load on my side. So I contacted telkom call centre about my problem and I was advised that I must send my prove of payment. I did send my prove and I was advised that my matter will be solved in 24 hours. Only to find out when I make a follow up that the advice was wrong. Today I called again and I was advised that I must go to the bank and report my matter to them. So why did they give wrong info at first. Poor service... My business suffers because poor service from telkom.
