WLS (the UKs number 1 aftercare providerby the way)don't do anything 'wrong' only right, as their many now slimline happy customers can vouch for. I won't tell anyone to go to any fill provider, (I do know of some stories of certain 'providers' going wrong too, but I'm not scare mongering on here or slagging any of them off).it's up to the individual who they go to. Just make sure you have a good 15 mins of advice with them before your fill, and can reach them for emergencies immediately on 24 hrs helpline. That they are well insured, experienced and professional. Good luck to everybody whoever you use. We're all after the same results, and can feel free to share our experiences on this forum
