Who to blame - Sanitas or Hospiten?

Amanda and I are expecting our first baby in December (the 9th to be exact!). We're both very excited and everything is going well - or it was until a few days ago! Don't panic, the baby's fine! We took out private insurance with Sanitas about year and a half ago, largely because we were trying for a baby and wanted to have insurance. We've been going to Hospiten in Estepona, as we know a few friends that have had their babies there and they seem happy with it. The appointments and scans have been good, you need to hang around a bit for you slot, but that's no issue. So, back to the story... on Sunday a friend of ours called us to tell us that Hospiten were no longer taking clients from Sanitas as of November 9th. Naturally we thought this couldn't be as simple and surely they'd let those pregnant women, who had been seeing the Dr's there, continue until the birth - so gradually phasing it out. But no! That's it! So now we (well Amanda!) is giving birth in about 7 weeks and we don't know which hospital we can go to. It sems incredible that this can happen and it's difficult to know whose fault this is, whether it's Hospiten's or Sanitas', I'm sure they'll blame each other! the options seem to be to go to USP in Marbella, or use the Costa del Sol Hospital. While I'm sure both are fine, it's crazy that at 7 months pregnant we should have to change all our plans and be left in the lurch like this.
