MTN ******, lies and spit on customer face with pathetic Service

I claimed from MTN insurance in April 2016 I was told that they were experiencing a backlog for close to two months without any feedback, due to the nature of my job I was forced to upgrade and took an LG mobile I was advise to insure this phone and once my claim is approved they will update the policy with the insurance after two months my claim was approved for 9000 and I went to the store where by the consultant assisted in me in choosing a Huawei Mate 7 I advised them that I will be using the mate as my permanent phone and will be giving the LG to my mom and would like to insure both phones. the store advised that insurance insures the cell number and must be in the phone that will be recognised of I chose the Huawei and they inserted my sim card on that phone since this day. the LG I was told to insure it at another store e.g Game of which I did. last week Tuesday my phone has been ****** and have been struggling to blacklist the phone till this day. I am told I need the IMEI of which I advised I no longer have the box was reffered to the store and the store refered me to the call centre. the store no longer has my documents and they advised me to call the insurance upon calling the insurance and asking for a copy of the policy document I found out there was just an IMEI number make and model of phone is unknown. I decided to google the IMEI number and found out that it was for an LG fone. my frustration is that the store has no details of the IMEI for my Huawai let alone produce documents that I signed when claim was approved. this phone is still not blacklisted I am not getting any joy. when asked why my policy documents were not updated after consultant did the update online while I was at the store I am told they don't know there is a new insurance company. whose fault is it? I don't even know where to go next I am frustrated very heavily pregnant and been paying insurance and MTN for bad service. the natur eof my job requires me to have a phone and I am unreachable to my clients. can someone please call me on 060 ********** I am gatvol with MTN I have been a loyal customer for more than 10 years but the kind of service I receive is disrespectful
