how to get help

Hi folks, feeling frustrated

During a biopsy at end of May i had a stroke, which was not diagnosed until 6 June. Mad MRI and saw neurologist 25 June. my stroke caused right homonymous hemianopia, Neurologist said i would need echocardiogram; heart ultrasound and opthamology appoimtments.

At this stage i haven't received any referrals for appointments and my GP has not had any correspondence from neurologist.

how long do you should you wait and how do you get them to do something. have tried phoning the hospital but getting nowhere
