DSTV - Selling Customers Data

Dear DSTV. You have misspelled my name and surname on my account. What's worse is that you have sold my data to other companies and I now receive SMS's and phone calls from telemarketers. I know that you sold my data because now they all use the same incorrect spelling of my name and surname!!! I'm not sure what upsets me more, the fact that you have my name misspelled on my account or that you sold my data to telemarketers.
