"Difficult to get appointments "

I always struggle to get appointments, I’ve had to pay for private Gp appointment on more than 1 occasion, I feel like complaints are not answered at times and when they are it’s not taken seriously, I’ve been waiting over a year to be sent to a long Covid clinic after request by Whipps cross hospital and I paid to see a private doctor relating to serious sinus and breathing difficulties, I haa as need in the recommendation letters by hand to the surgery and that has been ignored for the last 3 months.
