I had a Saturday booked 2 months in advance, 3 days later I was told I cannot have it due to changes in the organisation and the company will no longer be open on Saturdays so I had to have the Friday instead, I was not able to attend and asked if there was Saturday available and was told "its fully booked” I feel that I should have been called to fill back my slot for the Saturday. I do not live in the UK and I booked this Saturday in advance for a reason and now I cannot see the dentist until the 28th but the timing does not work for me now I have left with the same invisalign, I am not happy with the service at all and the incompetence of the surgery.
