Dr
Hello. I just wanted to mention some of the things that happened, so that your team is in the loop of what your customers are going through. I was contacted by Dr. Sadeq, which was very pleasant to communicate with. Roman on the other hand, was not clear about anything from the beginning. Saying “don’t worry, it is okay.” After confirming the doctors, and sending all my medical files 2 weeks ahead of time, I came to realise that the doctors have no idea about my condition. I walked in to a confused doctor, not even knowing that I have heart failure. I saw this as quite unprofessional that they haven’t even had time to review my documents. Once the doctor asked for my files, Roman did not have them, and I was forced to give a brief summary of what happened. This made me feel that my case was of no interest or importance to the representative. After finally managing to see the surgeon, he said that was the only day he was available (March 2nd), and that he was flying for work elsewhere. He had asked me to come back on the 16th of March. I could not believe that, as I have paid for tickets, plus hotels for two people (my mother joining) for 10 days in Vienna, when the doctor is not even there to do the surgery I was supposed to do. Do you know what the costs are of this mishap? After that, we ended up seeing another cardiologist recommended by the cardio surgeon. He was great, but when we came back the next day for ROman’s set appointment, it turns out there was no appointment, and he “had to go” and left me to deal with the hospital. The communication with Roman was horrible. I was just waiting in the lobby for 3 days not knowing what will happen, what are the fees, and no warnings or consultations. Especially when an x-ray costs 2,500 euros, I would have appreciated an initial warning of the costs. Not just “come pay” style that he has. That is as much as the biopsy, which I will still have to do in the future. I have experience with companies like yours, but the unprofessionalism, lack of communication, and unorganisation is unprecedented. I am going out of my way just to clarify what my experience was with your team, with handling things. The hospital and doctors were great. It was just the missteps by Roman that was upsetting.

I was not happy with Roman, the representative in Vienna due to many reasons. I have passed on my experience to Varvara.

I liked the doctor
I didn’t like the moment that we were eventually recorded to another doctor. I liked the doctor, but we did not have an examination, that is, only a consultation, in general I did not get exactly what I wanted. Lor did not like it at all, did not receive any new information from him, was not happy with the translator, most of what we said he did not know and did not translate

"Short but encouraging and 'productive' I would say
My hospital stay was short, my appointment with the doctor lasted for 15 minutes. He carefully listened to all I had to say, previous diagnosis I had, stated his recommendation and additionally prescribed me another drug. I have to do a follow up after I finish my medication and return for his opinion regarding my state of health. Short but encouraging and 'productive' I would say. However, I have the feeling we should have discuss more about side effects of the drugs and alternatives if they do not have the desired effect for me.
About Bookimed service
I am fully satisfied, I got instant help for may medical stay in Vienna. All details were clearly discussed from the start and what I was informed that will happen was totally confirmed. Sorry it took me so long to respond to your questionnaire. Congratulations to this professional team!
