Sanelisiwe Kunene (Mlambo)

There is a lady who calls herself Sanelisiwe Mlambo, says she's a sales rep from Old Mutual insurance, asking me if I want to change any of my retirement, funeral covers or get other covers, acts very friendly, saying how coincidentally her last name is the same as mine but her last name on Truecaller is Kunene, she's called me twice with different cellphone numbers from different cellphone providers, once on Friday, 30 June, and again today, 3 July. When she called today, she didn't remember calling me on Friday, I told her that she called me and I called her back but doesn't remember the conversation we had on Friday. I saved her number from Friday, and again today. I asked her why she keeps calling me with different cellphone numbers and she said that the other phone is dead and she's charging it. I don't trust her, please look into her, never have I received a call from an agent from a private number
