Telkom tiger valley made my life hell on that day to find out that they made a mistake and i need to pay for they mistake

i went for a cellphone contract last year June at tiger valley Telkom and everything was right i had all the necessary documentation and received the phone fill in the insurance papers and signed all the papers the consultant explained all the procedures of the insurance he told me that i am covered with insurance i then ask him just to double check again he then confirmed again that i am shorted i have nothing to worry about ,i then signed the last papers and got a copy off all the papers plus insurance papers and received the phone.....then two months after all the above i was on my way to work in the metro rail trains as i was about to get out by my station where i get off for worked i realized that my phone was not in my pants pocket anymore i then checked if i could maybe misplaced it and later found that it was really gone ,i then went straight to the police station to report that my phone got rob out of my pocket and they provided me with a case number and told me to take it straight to the telkom store , i then went straight to the store and spoken to the same person that help me to get a contract two months ago i explained everything to him and he started with apologizing and i asked him why he apologizing he then told me that he is deeply sorry for not contacting me two months ago to let me know that the insurance company send him a mail two months ago to informed me that the amount he provided to say that my insurance cost is for the phone i took on contract is incorrect and that it is more then what i signed that day two months ago , i was so shocked to find out that my insurer is not covering for the lost of my phone and he told me that there is nothing that they can do for me to give me the a new phone all because he forget to call me two months ago.he then went to his manager and came back to let me know that they can give me a phone but then i am going to pay for two phones the lost phone plus the new phone ,i did so because i was in need of a phone and was awaiting a call from a job that i app**** for the amount i paid for the two phones now is a lot and unnecessary all because off the consultants fault not to call me and to informed me about the mail he received from the insurer two months ago ,but to find out on that they when i went to go claim for a new phone from my insurer .

now i am paying more money for Telkoms mistake and then they also charge me a lot of money
