Help. My iPhone deleted all my contacts without warning
Help!!! My iPhone deleted all my contacts without any warning or action from me. I noticed a few numbers were not displaying with the contact name so switched the phone off and on to see if that would clear things. It didn't - it has deleted every contact that was on my phone.
I took it to my local Apple store who told this "can happen sometimes" and said "it was likely due to an error with a 3rd party application". When I explained that it had just happened and that I had not added any new apps I was told "yeah but sometimes this can just happen". How the **** can one of the worlds most popular smart phone just deleted contacts at will and Apple seem to have no interest in why this is happening?
Come Apple, I need your help.
iPhone 4S, iOS 7.0.4
