Bad customer service

I called Mtn last night spoke to Irene Mtsobeni to report my ****** phone,Irene guarantied me that my phone has been blocked,she told me to call back later to check if its done which i did an hour later only to find that the call center is closed. Called again this morning spoke to Zinhle Kabinde who advised that Irene **** about blocking the phone,she didn't block my ****** phone. And only to find out that my emails are being deleted by the person who stole my phone. Thanks to Irene for her poor service and her incompetency ,my private life on jepardy... such service makes one regard chasing Mtn as one's service provider.... am disgusted in Irene....
