Worst Service Ever Experienced

I upgraded my contract on 11 April 2015 and that is were everything went wrong. My SMS and Data was not loaded. I called the call centre, which i waited for more than 20 min to be assisted, and was told that this query would be resolved within 2 to 24 hrs. This query was logged as missing data. How does data go missing? 24 hrs had lapsed and still nothing, I called the call centre again and then was told orginal query logged would take up to 7 days. I then descided to purchase data, went to an MTN Store and purchased 1 gig of data. I was advised that the data would be loaded in approximately 1 hour. 3 hrs lapsed and still nothing. After 45 min on the phone with a call centre agent I was told that because it is a weekend i would have to wait until Monday for the 1 gig data to be loaded. Come Monday, still nothing. I again called the call centre and was told there was no resolution to my query and it takes up to 7 days to resolve. I have been waiting for 7 days for the first query to be resolved and still nothing. I sent an e-mail to customer complaints and received an automated reply that it would take up to 5 days for a response. What great sevice!!!
