FoneYam consultants unprofessinal

I took a device with FoneYam sometime last year. i had my first claim that was successful, on the 21st of June i lost my second device in an UBer going to work. i then called pone yami on the 22dn of june, o block the device, because i couldnt get it back. later the Uber driver driver was arrested and i got my device back. FoneYami insurence call me and asked if i i would want to continue with the contract, i the said i will pay the cancel and keep, i then called them to say i have done the payment in full but my device is still giving me an error code that its been restricted because it was reported ******. I then call on the 2nd of August, the sales agent told me to send an email with the screen short of the error message. on the 4th of August i then called again. Only to be told that they cant unblock my device because i have paiditin full, my contact number is ***
