I was taken by ambulance to Centro Medico on 12/2/12 because I was having a seizure. They said I had to be monitored overnight but needed to pay $2500 USD first as a deposit. OK, but I questioned why it was in US dollars and they said it had to be that way. (All my other charges in Mexico were in pesos) I had a blood pressure cuff on my arm that was attached to a machine. It didn't work. I had to convince the doctor that it hasn't worked in 1.5 hours. Finally he agreed to change it. The new monitor almost failed immediately too. When I told the girl about it when she came in to add something to the IV, she unplugged the monitor! They never came in during the night to manually take my blood pressure (yet my own doctor said that they had called in a cardiologist? for no known reason?) When I asked what it was they were adding to the IV, they said "potassium" . When I told my doctor, he said I didn't need potassium, but I could have used phosphorous - as indicated by their own blood results. At any rate, the IV leaked all night (from my hand I believe, because my bed was soaked). But I could tell no one because no one came in to check on me ALL NIGHT. Good thing my friend was with me to help me go to the bathroom because I was quite unsteady and unable to do it by myself. That's when we noticed that I was not getting any oxygen through the tubes to my nose. Looking at the canister, we saw that the small ball that should be suspended in air, was stuck at the top of the canister blocking the flow. No One came in to check ~ I was not getting oxygen. So I ask ~ what was being monitored during this time? On 12/3/12 they said I could leave, but had to pay my bill in full first. When I asked for an itemized bill, I received the attached invoice. When I asked why this one is in pesos while yesterdays was in USD, they could not explain. If I wanted more detail about the bill, I would have to request it in writing. Mind you they had this bill ready for me to pay within 10 minutes of saying I could leave. On 12/12/12 I requested a detailed invoice. On 12/26/12 I was told they didn't forget and it should be done by the end of 12/26 and they would scan it and send it. Because of the holiday, I waited until 1/2/13 to contact them again and ask the status; I have not heard anything from them. I'm dissatisfied with the non-care I received. I believe I was kept overnight just to inflate the bill. And the bill I did get cannot be justified as is evident by their lack of cooperation in producing an itemized bill for a bill they had calculated on 12/3/12. I would appreciate any assistance you can offer. Thank you. Patricia Guzowski [protected]@comcast.net
