Audi Audi dead from we buy cars silverlakes After 1 month of driving. Useless dealer

I bought an Audi A4 2003 model from we buy cars. Car died after a month. Engine was declared dead by experienced mechanic. We were advised to buy a new engine of 26000. I reached out to we buy cars to inform them of my grief I never got a reply. AJ at Silverton told me I'll be wasting my time taking this up with them as vehicle was 2nd hand and I won't be remedied. This left a very bad taste in my mouth. Don't buy cars from we buy cars. You're on your own once you start experiencing problems. I'm never going back there. They are useless. 🤬🤬🤬🤬
