I handed back my car last Friday, had it for 3 years and then extended. In total I’d had it 3yrs and 7 months when I handed it back.
I got the £350 payment previously and have just been emailed to say they’ve paid a further £250 into my account.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
