AXSURE and RENASA POOR SERVICE

I was incorrectly charged an additional excess fee which was not applicable to me and I inquired about the same and I was notified that I would be refunded as the additional excess was not applicable to me, upon inquiring about the date when the refund would be made I started not getting responses, I sent million emails already and I have not been getting any responses, the matter probably dates 3 months ago, and up to date the is no response, their service is pathetic, they either unilaterally decide to increase premiums, alter terms without notifying you, and mostly you never get any response on their line, it just cuts you immediately, their service is extremely poor, even the so called managers are so rude, I went to their underwriter's office RENASA and they were also not helpful on the matter despite being AXSURE underwriters, if anyone is still with them please look for something better before it's too late.
