Insurance MTN Taking too long and No feedback

I had my phone ******, I tried to blacklist my phone the next day but they never helped me. So i eventually got my phone blacklisted, i got all the paper work in line. I submitted my documents in an MTN store, the lady emailed them i then emailed them the documents my self. i haven't since received any feed back. i got the paper work to them on the Sunday 7th of February and was told that it takes 7 working days. it is already the 23 of February and i have had absolutely no contact from MTN. i also have been calling for the past two days and wait and wait for up to 40 minutes. and still no come back. I have emailed and still no response.<br> <br> What can i do this is outrageous.
