Sorry, name changing old timer to protect my RL identity on here (yawn, yes I know- please feel free to quiz me on MN howlers past and present)
I was shopping on a busy saturday in a chain. A lady approached me she was the manager.
She introduced herself and said she wondering if I would help her as she'd had no luck for the last hour and needed a candidate to take part in a radio phone in show- prizes/money going to charity and their staff and the chance to win an electrical appliance for myself???
I asked how long it would take and agreed as long as it would be swift as I felt a bit sorry for her 
- I also asked what charity it would be for and whether it would be filmed? She was vague and said she wasn't fully briefed on the details. She then laughed and said that this was very much the "style" of their company. That they were very up on motivation for the staff, crazy competitions, incentives etc. I took this on trust and they are a very big company.
We went to her office and the phone rang on speaker phone- radio guy with jingles in background etc- asks me where I'm from, age, name etc.
It was then put on handset and I had to answer a few qs and agree whether or not to perform some silly tasks (think Chris Evans old style larking) some I did some I refused (every refusal got money for the charity)
Anyway- fast forward 20 mins and I cut ot off (as I wanted to go and was stretched for time. I'd won ££ for charity, 2 prizes for the staff and a prize for myself to be collected from the store on the following Tuesday and £3000 worth of stuff.
I was really pleased and as I fundraise for a local charity I asked if my prize could be donated to my chosen charity as well as thiers (I've got no need for another toaster of cake mixer 
) I was told we will see on Tuesday.
I arrive on Tuesday (this place is a 55 mile round trip for me)
The manager looks solemn. She takes me to the office and tells me she's been stupid, it was a hoax, nobody was coming in.
She gave me a £20 voucher for my girl (it was her birthday) and asked me to leave. 
I've since called their customer services to demand an inquiry into her behaviour and to get some token for being humiliated, out of pocket and time.
They've not called me back.
They've said they're sorry but these things happen????
I've nobody except my close friend to asked and he advised me that he'd be going for the complete amount of things I was promised and to not compromise.
So your feedback would be greatly appreciated.
