No incoming calls!!!!! and sms!!!!

On 4 August i discovered that my number was ******. I went to Menlyn store and we found out that my number was with MTN . MTN then reversed that porting process(i didn't port). I have my number back. But since then i cannot receive any calls. I can't send and receive smms's. I have been to the Menlyn branch 4 times and called your 081180 number numerous times. They did all the troubleshooting but still nothing. I have a few cases logged now. Still nothing!! Please email me **********
