Nonsense service

On 05 December 2018 my iPhone was taken in for repairs - a week later I received an sms notifying me that FMIP is on - this is obviously untrue as I have never enabled it. I've logged onto FMIP using a different iPhone; as well as onto iCloud to check this - and its off!! I have been on hold with the call centre trying to get assistance to no avail! After holding for about 10 minutes my call was dropped!!! Nobody has been communicating with me since my phone was booked in and I'm unable to get telephonic assistance. Service is horrific!
