"Unable to get a face to face appointment"

Have not seen my GP for 18 months or more, to get a telephone appointment takes up to 3 weeks, I have multiple myeloma and should have regular checks but these don't happen, after blood tests are taken I phone to get results and then maybe told I need to talk to my GP, who may not be available as I have said before for upto 3 weeks, the whole situation is totally unsatisfactory. I am disabled which is another complication. Have rheumatic and back issues, recently asked for a GP home visit, he didn't come but sent a lady who wasn't even a GP. Would like to change surgeries to one which is more accessible and hopefully helpful.
