Leapfrog poor services

I viewed a house they have up for rent and I wanted to apply, the estate agent is giving me the run around, upon asking for application forms he told me there was already applications put in and he will contact me should none of them be successful, but that I could email him a copy of my ID which I did. He never contacted me. My husband then phoned him and he said the house was taken and deposit was paid. Something just did not sit right with me and I waited for a few days after that and got my daughter to contact him asking if the house was still up for rent and he said yes, we arranged for a viewing, this now being the second time viewing the property. Again he said he would email me the application and for the second time asked me for a copy of my ID which I supp****. I still have not received an application form. The applicants salary is 3 times the rental amount and both have credit scores above 600 and have all money's needed for deposit and extras, so I don't understand what the problem is. This estate agent is incompatent and it seems that he wants to service only surten population groups. This is unacceptable.
