ESA CB and NI CONTRIBUTIONS ???

Hi can anyone help with my query. I was in receipt of esa ib and claim began in 2014. I was also awarded DLA and PIP and get enhanced for care and mobility. Because i lived by myself at the time i claimed the carers allowance as i was entitled to do so and i believe i received such - i think my payment at the time was about £360 a fortnight from dwp. I stopped claiming carers allowance 2015 - the end of the tax year as i moved in with my son who then claimed the carers allowance. I cancelled my claim for esa this april 2017 as i married and did not think i would be entitled to esa ib anymore as my husband works. Anyways after a conversation with a friend they told me that i should be able to get esa cb as i will have had my ni contribution paid while in receipt of such benifits. i have checked my ni status and i have paid full ni contributions since 2014 but i understand there is critiera to meet. Can i get esa cb on my benefit types as above please as i really dont undetstand it - sorry. I did work full time upto 2007 and paid ni but havent been able to work since. Thank you for any help and advice.

Hi update I just phoned hrmc and they told me Dwp have only paid me class 3 national insurance contributions I am so confused as everything I have read says I would get class 1 as I was on esa ib and they also told me I have no carers contribution so what did I get please-severe disability premium????

Thank you Gordon I must have had the sdp which is not good news but nothing can be done I thought I had claimed carers for myself. Don't understand why they processed a claim for esa cb though that's daft and a waste of time was on phone to them for two hours lol

Sorry to be a pain but if I was able to earn a living from home. I used to sell books online. In the future would class 2 self employed contributions qualify me for esa cb if so how many years and which class 2 thankyou
