I have dstv internet I normally pay on the 25 and my data is normally loaded or the next day this month though I didn't receive my data I called the call center and the lady hung up on me, I called the next day another answers and the problem would be solved within 4 hours and apologies but two days later nothing I called again the same thing, I wrote an email to customer care thy responded and apologized and also told me it takes 4 hours to load data it day 4 today still no data, I paid for the data that I didn't receive I'm so disappointed by the service I told them I want my money back but even today thy tell me the same story.
