Unresolved proof of payment

I am very furious with the service I am getting from MTN ,I have been countlessly sending proof of payment in order to have access to my sim card and claim insurance for my ****** phone ,however no one seems to be assisting I have been sending proof of payments to Lwandile Lushaba,Kim Damon,Mapaseka Mokoena ,Cedisile shabalala,sihle Daimani,Asanda Moyana,Thabang Dondolo but none of them seem to be compatible enough to assist, I am spending a lot of money trying to have this resolved, this is disappointing and I need my phone
