Estate agents

Is it normal of estate agents to ignore you?

We're looking for a new rental, can't afford mortgage yet as I'm still studying for my career while being a sahm, have 2 kids but my partner works.

His income alone can support us but currently we're living in a family members house (which is huge BTW), have been paying rent and utilities etc. But it's getting pretty intense, I feel like 2 families under one roof will end in a disaster so we're wanting to move before shit hits the fan as we still have a good relationship.

This is our first time dealing with estate agents and we only have limited options right now as our son goes to school here and my partner works here too, our son loves his school and has lots of friends here so we don't want to pack up and move too far, his only 4 but I moved alot as a child and it was hard on me never having any long term friends.

I contacted the estate agents about a house that would be good, this was 2 weeks ago, I emailed them first as the listing said to, 2 days later no reply so I call, they said its still available and to email again, so I emailed again, still no reply, so I call the next day to find out its been taken. I find another house which is even better, again I email, no reply, next day I call trying to be quick, they said they'll email me questions so they can put me on the database, I answered all questions within 5 mins of getting the email, no reply again, I email again asking to view it, no reply, I call and they apologise saying they're busy and to email again, again no freaking reply! The house still says available on their website but I doubt it is, I walked passed it yesterday and saw people either moving in or moving out, not sure, they emailed with a brand new listing, not even on third party sites yet, I replied back immediately saying I'm interested and want to book a viewing, NO REPLY!! I really want this last house, it's only a 10min walk from school, 15min walk to partners work, it's so big, modern, beautiful garden, whole house is just gorgeous but this is really stressing me out.

This is the only estate agent that works with this area with nice houses, but all I've ever gotten from them is questions for a database, "email us" or marketing emails. It's been 2 weeks, 3 houses I've wanted to see but nothing is happening.

Is this normal??? I've called and emailed them so many times, I don't want to be nagging them
