Go to the BAA (banking association who regulate financial practices in the uk) with that & kick up a fuss. Go to BIS (dept of business innovation & sports) & complain. maybe the finance ombudsman can help?
You might be confusing level 3 being A level/AS level with 3rd year university. Use national careers service.
A level is level 3
university 4, 5, 6
i don't get how you get a degree with "access to h.e" as it is a year 0. in a 4 year degree, you have 0, 1, 2, 3 with the 0 year being the entry year. Some universities have this as a stand alone diploma. Most people take access to h.e as they don't have any formal study after gcse or don't have proper a levels.
I have a business access to h.e & I was able to go on to an HND (1st two years of a degree) or BBA in this case. Definitely complain to some one. Get your local councillor where you live or draft a letter to MP in London. It must be the MP for your residential area of the UK.
Good luck. Hannah
