I pay R50 for 200 sms's per month. I have noticed that a unknown number has been used on my account. I queried it with MTN but did not receive any feedback. This has been happening over the last 5 months. The cell number which is used on mu account is 0839300006. When i dial this no, it says the no is unknown? What is happening here? My cell no is 0833011307 email [email protected] read full review »
