Hi daisy happy,
I no how desperate you are feeling to have the op, trust me I have been there. But and this is a big but, you have to feel confident in your provider. This op is a big deal and you need to no that you will be safe and cared for to the highest standards.
Please, please consider getting a refund and come to England to have the surgery. I like several others went with the WLS group and have only positive things to say, and they are really reasonably priced with an excellent aftercare package.
Maybe someone on here that lives in one of the relevant treatment areas could put you up to keep costs down? You could use a budget airline? Surely these are options that are worth considering. They did my op within a month of my first enquiry, so you wouldn't wait long.
If you decide that you want to continue with the op, then phone the company and ask to speak with either the surgeon or another member of the medical team that will be looking after you to help ease your concerns. The other alternative is companies generally offer for you to be able to contact people that have already had surgery with them, to get a patients perspective.
Good luck.
