General Woes of Student Life

Last year we found the most perfect home; a three story converted pub split into two apartments. We were told it would be finished by June 2012. But when I moved in on September 7th, there were several things that still weren't finished. We'd been messed around by the estate agents for so long over summer, so by that point we were hoping it would all be over soon and we could cease contact with them. It's now November and we still don't have a proper entrance to the property, by this I mean- there is a small ally way leading to the gate to our garden with no sign saying that number 53 is in that direction and we have no post box or doorbell (let alone the intercom system we were promised). Although everyone we know is completely jealous of our beautiful hardwood floors, brand new appliances and the sheer size of the place, I just feel like this isn't going to be a good option for next year. I've just been into the estate agents now because apparently we need to pay to book the property for next year, they were supposed to send us a letter, but how the hell would we even receive it? When I went in today, I was told I couldn't pay this booking fee because two of my house mates were in arrears- specifically for £65 each as a deposit on the spare room. I'm pretty sure nobody owes anything as we've all paid the same amounts. I was also told that the reason they hadn't asked the landlord about a letter box or doorbell was because two people were in arrears. What a ridiculous excuse, we haven't had a letter box for two months but they only contacted them this week to say they owed money. I'm at the end of my tether with them and I know my house mates are too. I was also told today that our rent would be increased for next year. Since I get the minimum loan and am paying 1/5 of the rent on the spare room plus £75 per week, I am terrified of running out of money completely and having nothing to live off. I don't really see the need to live in a house bigger than my parents anyway.
