you pay your deposit then the balance has to be paid 56 days before your surgery date.
i payed my deposit in april, the balance in september and my op is in november. ask your pc, she will tell you what dates r available in the future
then you’ll know how long you have to save, i thought i wouldnt have all the cash in time and my pc said they could rearrange my surgery date and give me another 6 months extra, but luckily i found the cash, so dont worry too much, they are flexible.xx
