I see a pattern in the issues here as I experienced the same thing: no internet for weeks and rats. I was completely and utterly ignored when I contacted them about it (multiple times). The only time I could get a response out of them was when I asked about vacating the property before the end of my contract (what a surprise, they only reply when money is involved). They agreed with me over the phone that I wouldn't have to pay for cleaning because someone else was taking my place, and yet as soon as the deposit was due to be paid back they gave me a list of 100% fictitious expenses (including an over-the-top charge for cleaning!) I have never been anything but a perfect tenant, they lied to my face and betrayed me and took my money. Of all the estate agents I've been with, AB-FlatMate are the absolute worst, they will try and take your money and they will stab you in the back at any point. It is completely clear they don't care even slightly about their tenants, only about their wallets. They are bullies.
