"Poor communication/follow up"

I called GP surgery as advised at 8am in morning and spoke to receptionist at 815am regarding pain medication review and concerns that my sick line was away to run out and no improvement with medication. I was advised that I would  receive call from GP in a short time to discuss.  I received telephone call 3 hours later from receptionist to be told I would need to book an telephone appointment this week as no appointments were left for today despite me already booking one this morning. When telling receptionist I had already made appointment she explained she was only advised to call me and that she would go back and discuss further then get back to me. Later in day, I was advised by telephone call from another receptionist that I could get telephone appointment next day, I again explain my appointment was made this morning and I was expecting GP to call. I highlighted that I realised it was not receptionist's fault, but the system and as I work for NHS this delay is impacting on my own return to work. 

I felt that despite calling early to get an appointment my own health needs were not being met. Despite the receptionists being understanding and compassionate it is very frustrating that the system is very unfair. With patients being told to call in at 8am to make an appointment and advised they have an appointment, to be then told that they need to make another appointment as there are no appointments left? 

It is very confusing for patients and I understand  from what receptionists have shared that there are staff shortages, however this service at present does very little to reassure service users that their health worries are being listened to and their needs are being met.

I am aware that the NHS in overwhelmed and understaffed and as a health professional it is upsetting to experience this type of service as a service user.
