BAD SERVICE!!

I've been with Hollard Ooba insurance for years,I had a bond protector policy I've missed one month premium and I was told my policy will lapse if I don't make a payment.A payment was made and I did send a proof of payment but to my surprise was told my policy has lapse! Tried to solve this matter with one of their agent but was sent from pillar to post till to date. I've asked for my June refund since the policy lapsed and told them to cancel the policy and send me a cancelation letter,they're MUTE and no one is communicating with me regarding this matter! I wouldn't recommend this company to anyone!!!
