BAD SERVICE - REGENT IS IGNORING ME

client of regent bumped my car, it was a car from the dealership. they registered a claim for me in May. I also contacted regent and they asked for documents, i sent them to K****tso as per request and they kept quiet. she didn't confirm receipt or acknowledge my email. i did a follow up the following week, she then rep**** and asked for more documents. (why didn't she reply when she received my email) i sent outstanding documents and she kept quiet as usual. i sent a follow up email to find out what going on, she didn't respond. i called regent the guy i spoke to told me he cant access my claim he will put me through to K****tso. i held on the line for 15 min, i had to drop the call. This clearly tells me that she doesn't care and no one cares at regent. even today i haven't heard anything from them. whether i call or email them i am getting no joy
