>>>"but have no contract"<<<
Oh yes you do! Whenever someone agrees to work for someone else, a contract automatically exists between them. (If I offered to do your shopping for a fiver, and you agreed to my offer, we would have both entered into legally binding contract).
>>>"or written statement"<<<
Well that's certainly illegal. All employees should receive a 'written statement of employment particulars' within two months of commencing their employment. The fact that you've not been provided with one most certainly doesn't invalidate your contract with your employer.
The information here, about being 'laid off' due to insufficient work being available, might be relevant to your situation:
