"Cant get through on Phone to Locala"

I have been trying to get through to the podiatry service to book an appointment but cannot get through. I’ve tried at all times of the day – it says it is a 24 hour line so have tried at 5: 30am when I get up for work, during various times of the day and 11: 30 pm on Sunday. Surely there cannot be so many people all trying to get through at extreme times? In desperation I asked my GP Surgery to try, they could not get through either, they tried for two days. To add to the frustration a letter dated 4th Feb was not received until 10th Feb and this has eaten into the three weeks’ timescale I have for making my appointment or being taken off the system, presumably I then Have to go through and have a new referral from my GP, wasting their time and resources and further delaying my treatment.
