Issue with lost Data

I am really disappointed by the service i received from MTN regarding lost data. My husband lodged a complaint about the fact that he has lost data, by calling 173 and spoke to Rebecca, who told him that someone will get back to him within 24 or 48 hours. <br> <br> 10 days later and nobody got back to him yet. The complaint was lodged on the 7th of March 2016<br> <br> I called this morning and spoke to Joseph who, first told me that there is no record of the call with Rebecca, hence he cannot assist me. I then told him that we recorded the call because we have an app to do so, so he had better find that communication because it is already 10 days and nobody has attended to the issue. Eventually he found the details pertaining to the call and said that he will escalate the problem and someone will get back to me within 2 to 24 hours.<br> <br> Nobody has gotten back to me yet and I am hoping that someone will attend to my issue asap.
