What other way can I get into Junior IT Support Role

Hi I would like some advice please to what jobs should I apply for if I want to do a IT Technical Support Job in the future. I have picked up most of the skills in past retail jobs for example working well with one and other, analytical thinking skills, having attention to detail, customer service skills and even verbal communication skills. Although since becoming a postgraduate I’ve applied for Junior IT Tech Support roles although sadly the response has not been positive so I was wondering do I start myself off low working at call centres/receptions or offices before making my way up or what advice would you suggest and are there any specific websites, places that takes on graduates on a Junior role

I would apply for entry level jobs in IT tech support. Working in any other role would not likely help.
The rule of thumb is directly relevant skills is preferrable over transferrable skills.

I am not sure if you have a degree in something related to IT. If you have, you can try to apply for the job as you are.
If you don't (and even if you have), I would strongly recommend getting a professional IT technical support certificate recognised by the industry to help, as the knowledge on the certificate is more relevant than what you get on any degree. e.g.

There are more lists if you search on Google or YouTube..

Personal preference, I would either go for Google IT Support, CompTIA A+, or the IBM's certificate. Which one you go for is up to you.

Ultimately, the employers in the space as far as I know look for people with experience more than people with qualifications. If your experience closely matches or mirrors what they specifically need, you're put in front of the queue.
If you're having problems getting jobs through application, then I would strongly recommend you network your way in
Also consider getting roles in IT shops to see if you can get some experience in hardware and software maintenance. Whilst these are jobs directly related to IT support as you find in call centres, the job is far more relevant than say retail, call centres, and office work.

Hi I do have a degree in something IT related though that’s at a 2:2 although I want to start off low with gaining experience before building my way up especially considering the grade I got within my degree.

I don't think the grade would matter too much (I don't work in HR for tech); it's more of the fact that you lack experience.
I would just keep applying as you are. If it's difficult, then I would try to network as much as I can.

Note: if you did an IT degree, then you should know classmates who got jobs in tech (or at least know of people who work in IT support). Have you asked them to help you out or at least give you some career advice?
