Urban Company — Unsatisfactory bathroom cleaning service

I booked 2 intense bathroom cleaning and none of them were cleaned as per the description. I booked revisit but no one came for revisit. I have been called back by customer care minimum 6 times and everytime i have to explain them what was not done. I was asked to share pics which i did and I am promised a call back in 10 min and the callback is done after 48 hrs. I need full refund of money or someone should come and clean the bathroom as per the description provided. Everytime i am offered a refund of either 200 or 400 or 450 or 499. My question is why not full? The last call which came today was intentionally disconnected by the customer care because i was asking for full refund
