Very Concerning - Bad Service - Invasion Of Privacy

My husband received a new iPhone XR through his company business contract. 3 weeks after receiving his phone it started freezing and stopped working. He called in for them to collect the phone and requested a replacement. MTN kept his phone for 5 weeks without another loan phone.. he had to use our 12 year old sons phone. (Which leaves us in a concerning position of not being able to contact him) After loosing it with MTN they eventually “replaced” the phone. He received his “new” phone on Friday via a courier... on opening the packaging the iPhone box was NOT sealed and we could see that the phone was not new. When starting the phone up there was someone else’s profile on this phone (we have picture evidence of this) By Sunday (today) two days after receiving someone else’s phone (with their profile) the phone has now switched off and will not turn on!!! He flys out of the country tomorrow morning and again doesn’t have a working business phone.. I have mail them to explain the situation, however I’m referred back to the call centre who is unable to help because this is a business contract. #mtnsa #mtn #mtnbusiness #mtnservice #privacyofinformation
