If you've sent an email asking for them this means you have put your request in writing. You could send one more email, with 'Subject Access Request' in its subject line, saying something like:
To whom it may concern - please raise this matter with the practice's 'Data Controller'
I would like to receive a copy of my records, covering the treatments I received between 1st January 2024 until the present <or specify the period of time>.
My details: <include your full name, address, phone number, NHS number or any patient reference number they've given you, so it's clear exactly who you are>
I already put in a subject access request, on xx October <whatever date you first asked - which could include a verbal request - in which case, you could remind them that you followed this up with emails>, and understand that you have a legal obligation to provide me with this data within 30 days, ie by xx November.
I would appreciate it if you could send me my records as soon as possible, by email/ post <depending on what you prefer>. Alternatively, I will come to the practice in person on xx November to collect a print-out from you.<again this depends on your preference - you are entitled to be sent the info in whatever format suits you>
Thank you for your help with this matter.
If they don't comply, you could then turn up on the date you threatened promised to...
There are a few exemptions that organisations can claim for not supplying this info on request - eg if they think you are asking on behalf of someone else and don't have their permission to do so; if you've behaved unreasonably, and made loads of requests of them as way of harassing their staff
