What to do about a dud realtor?

[Jesse Aaron]

I’ve made an offer on a house using a realtor I had met only once before (I’m new to the this). She seemed great until my offer was accepted and I signed the contract. Since then she’s hard to get in touch with, very short and seems disinterested. I’m in my last day of the inspection period. The inspector found a few issues (see my post about electrical concerns) so I made a second offer earlier this week asking for a $1,000 allowance after closing to help cover the $3,500 quote the electrician gave me. The realtor won’t answer the phone. I texted “have you heard anything? Don’t we have to make a deal by the end of the day?” She writes back “no an yes.” What do I do? I’m in too deep to fire her. I’ve already signed the contract. Do I go over her head and try to contact to sellers realtor? What happens if they just ignore it? Is the deal dead or am I held to the original offer even tho it was contingent on the inspection being satisfactory?
