Angry customer

Worse service ever .... In 2019 I took out cellphone with Telkom and put them under insurance. The contract ended in March 2021 where I cancelled one contract and upgraded the other. Both devices continued to. Deduct in December I went to put in a claim of a lost device the last I received an email from them was when. They asked me which SIM was in the phone I rep**** by telling them I cancelled the contract of the SIM after 2 years ...... They HV being deduct my salary using a code that substituted the number now after not hearing from them 4 over a month I called only 2 hear my claim was regreted..... I have been sending emails and calling no one knows what to say besides they will forward my request 2 claims..... Emails they don't even respond to them..... Can finrite please replace my lost device or give me my premiums since March 2021
