"Problems trying to arrange to have my implant removed"

I called the Mottingham clinic today as I desparately need to have my contraceptive implant removed and wanted to enquire whether I could have this done if I just attended teh drop in clinic on a Wednesday or if I needed an appointment. I have a full time job, a baby and a 2 year old, so need to make a lot of arrangwements in order to attend the clinic. (When I went to have it put in I waited for 2 hours) So I wanted to understand if I made these arrangements then could I have the procedure done or would I need to go back for an appointment, per the advice on the website. The person I spoke to was rude, told me 'they are not here', 'I don't work for them', I advised I was despartae for help and asked who I could talk to, was then bluntly told to go to the beckenham clinic today, when I had already explained my situation with work and childcare. Eventually I was given the number to call for the Beckenham clinic, which doesnt help me as my enquiry is relating to whether I can have the procedure tomorrow at Mottingham. The person was rude and short with me and the conversation left me in tears.
