Is my managers no response a sign?

Hey soo basically I am employed by JD the thing is on my induction day I was never given a contract to sign on paper and was never sent one by email either we just discussed that I am a Christmas temp working on 16 hour contract… I do have my managers number and I phoned her this morning to say that I have decided to leave the company due to Pressure, stress and the busy time which concern me…

I have mental health and anxiety and I can’t focus on more than one task at a time realistically JD required being observant and can end up with police being involved if things got really bad… so I decided to leave and go back to my old job. Thing is I have messaged my manager about this situation and I still got no response from her I do not know if she has seen it.. I’m pretty sure she must have as when I messaged her yesterday she responded… so I didn’t turn up to my shift which was at 9 and I still got no call asking me why I did not come in or a reply I’m starting to wonder if I am being ignored….

I want to give her a day or 2 just to reply back to me if not I am going to March over to the store and sort it but I think she has seen it and has acted on it….

whar do I do

It has all been dealt with now I have moved on and not being funny but the place is JD sports it’s kinda common for them to just ignore us I spoke to their head office and again was told to speak to a manager which I did and she’s seen the text and removed me off all my shifts I take that as a hint that I’m off the system.. like I said I never had a contract to sign with the company nor was I sent anything by email that’s how I managed to leave.. my sister works for HR she's helped me out
