We have been issued a section 21 to end our tenancy as the landlord wants to sell. The rental is via an agent and they have been pretty useless, the section 21 while coming to our address actually states a completely different address. It was issued on 9 July and we have been looking for somewhere to move since but we are really struggling. If the worst happened and we could not find anywhere could we 'bring it to their attention' that in fact we have not been served notice as the address is incorrect ? I don't want to do this as it will probably affect our references and chances of renting again but just want to know where we stand.
