HALF A DAY WASTED AND NO SERVICE

My phone was ****** this morning. <br> I have since spent the entire day trying to get hold of MTN to get the handset blacklisted so that I can get a case number and have the phone replaced. I cannot get through to MTN Insurance and when I do they give me the incorrect IMEI number so that after 40 minutes of holding trying to get through to MTN to blacklist the phone I am told that they cannot help me with the incorrect IMEI number. I have wasted an entire morning on the phone with MTN trying to sort this out and I am no closer to getting this resolved than when I started out. Calls are continuously dropped after 15 minutes plus of holding!!! What are we paying these high rates for? This is not service!! THis is disgusting!
