Lendy hung up on me

I received a call from Lendy on the 02/02/2016 9:20. She called me on my landline, said she is calling from Cell c and asked me to give her my ID number. Since there is too much ***** i asked her to confirm the first 6 digits of my ID and i will confirm the rest. She said that if I wont want to confirm my details, she wont force me too. She was very passive aggressive and rude (speak in a soft voice as though I wont sense that you where rude). While i was trying to explain to her why i cant give my ID number and asked her to ask me another question, she hung up me. I then called to lodge a formal complaint of which i was transferred from one department to the other. After holding on for 40 minutes for legal, i was told i need to call early recovery and that's where Lendy works. I called that department to speak to her manager and the gentleman told me to call customer care and refused to transfer me to a manager. Look this is not the first, 2nd or 3rd complaint i have has about your stuff. it is unacceptable, pathetic and belittling. I would like her to call me and apologize and also send me an apology letter for treating me like trash and ruining my mood!
