Reported a leak to our letting agent (months and months and months ago), they never sorted it despite several responses saying they would get back to me. Eventually I informed the landlord directly by writing to the address on our tenancy agreement and the agents were in touch straight away.
They said they would speak to a contractor, check his availability and then come back to me to arrange a time.
I heard nothing for over a week and the leak was still ongoing so called again to be informed that they had sent someone round nearly a week ago who had replaced a part in the bathroom.
Firstly, the repair clearly hadn't worked but secondly, I'm sure they cannot just hand someone keys to our home without checking first whether it is okay?!
I hate to be one of these 'what if' type people but what if I'd been in the shower or just walking around in my underwear or in bed with DH!

They would not have even told me if I hadn't called back to check what was going on because the leak was still there!
They are completely useless on all accounts to be honest but this has really annoyed me. I feel like I can't relax knowing they'll happily just let people in without my knowledge!
