iphone stops ringing then rings again
Hi! My iphone X will ring when a call comes in -- if I decline or turn down ringer, the call will stop, but then the call comes through again some times a total of three times. It's bothersome. One time, it happened when someone I actually know called. I asked why he called 3 times and said he actually only called once. Any suggestions on how to fix? Thanks, in advance.
