"Not fit for purpose"

After nearly 2 months of illness - approx 1 month with a virus then a month of post viral fatigue and still feeling ill I contacted the surgery via their get-help section. In my message I explained that I was still unwell and wanted to know whether it was likely to be simply post-viral illness or could I still be infected. I also wanted advice about whether I should have the covid vaccine when unwell. The doctor's response was to wait another month then he would consider a blood test. My other question about the vaccine went unanswered. I am 73 years old, and I don't think a simple blood test to rule out infection is too much to ask. I had been treated at Wythenshawe hospital initially in November who had found abnormal blood results indicating infection, and had prescribed a course of antibiotics. Being told to wait another 4 weeks I think is shocking. They could at least have phoned me to check how I was & what my symptoms were.
