Installments changed

We have been battling with Budget insurance for a couple of weeks and this is becoming frustrating. Their service is very dissapointing. We put in a claim and eventually this was paid out after going through alot of trouble. After providing proof of 7years insurance to various consultants at budget they are still claiming we only have 3 years insurance proof. They increased our monthly installement and deducted the money after we provided the evidence they required from REgent to proof that we were insured with Regent for 3 continues years. According to them that was all they needed, now al of a sudden they need some other information as well. They are useless and we need to phone them the whole time. We have never struggled with service like with Budget insurance. So many people have been dealing with this case and everytime when we speak to someone no one knows what is going on. Not professional at all.
