We visited my brother in law who was rushed to ICU. An incident happened on the premises of the Hospital Theft in my vehicle as we arrived at 19:15 when we came out at 20:19 I saw that my passenger door was open I immediately reported it to the security. I found that my wallet, work tablet cloths we brought for the patient as well and Radio was ******. It's seems like that they denied that it didn't happen on their premises as they said their are no concrete evidence that the vehicle was broken into on their premises. I asked who will compensate me they used the disclaimer that exhorted them from owning up. Their place were supposed to be safe as they have secured paid parking and visible security on site. The theft happened within an hour ( visiting hours) no visible security and no one saw nothing. Today when I went to see the hospital manager I was directed to see the service manager who didn't call me today to find out or apologize for the inconvenience caused on their premises. A man brought in a patient who had a heart attack the security was unprofessional by telling him that he will be clamming him for parking in the paraplegic parking. The man explain that it was an emergency and will remove the car when he came back. Poor service. I was not allowed to view the security cameras. Heinrich January
