Part time Job help!!!

Hello,

Kinda new to this but I need the information because I've been apply for part time positions to work during and after summer when I am in college tirelessly for weeks with minimal success (17 years old).

I've been reading through many threads about peoples success with obtaining part time jobs and I was wondering if people could post lists of the names of the companies they work/worked for in London whilst in your teenage years. I understand there may be issues with privacy but I only need the information to know where to apply to and it would be significantly helping me out.

Preferably companies in industries such as Telesales (Call centre), Retail and Hospitality (Waiting, Barista etc).

Greatly appreciated, thanks.
