I currently rent a house through a popular letting agency. On Monday someone has clearly been in my house, I come back from work and my front door was locked, but, not normally how I lock it. I am the only person with a key to my house apart from I assume the landlord? And the letting agency. I called the letting agency the following day (Tuesday) as they were closed that evening, and I spoke to a manager there, they claim over the phone quickly that it appears no one has been round my house at their end. They said they would investigate and call me back. No call back. Today I called them again, apparently management were busy, and they were going to call me back. - No call back. I am concerned about the property that I am renting, if the agency have not been in my house, who else has a key to this property? I am concerned not only for my items that could be stolen very easily (someone has already been in the house, I have no idea if something has already been taken?) and also mainly for my safety. I was going to call them again tomorrow, but I feel via phone I am not going to get anywhere. It is a weird situation to be in, what steps would you advise, and I am likely going to try and visit the letting agency in person and go in. I guess asking for the locks to be changed is a start, but it would be nice if the agency actually cared. Two days without a call back is unacceptable. *Additional to all of this, we have a damp problem with lots of mold in the house. This was reported over 5 months ago. No care from Martin and Co there too. No one has been in to check it, quote it or repair it. They are just leaving it to get worse. **Recently, the boiler has broke, I have no hot water or heating in the house.
