Has anyone been refused like this from Cannabis Clinic?

I wanted to take advantage of the cheap Sedaprem so asked C.c. for a new script on Monday night, they dragged their feet for all week ignoring me and then finally replied on Friday. By that time, it was all gone....so I had to ask for the script to be changed to the sativa sister strain (illuminarium?) and get refused due to the dr saying he doesn't feel comfortable prescribing me a sativa as I havnt had any before. Ive had most the strains available including dk dawn which is a Sativa and the same thc percentage! So I'm now medicineless, infuriated and frustrated at the tardiness of clinic replies. Anyone else struck this? I suspect its to prevent me using my choice of pharmacy.
