LAPSED COMMUNICTION

On the 12th July I sent OM an email to move my debit closer to pay day as it went unpaid for July. 4 days later i get a response that my policy will lapse... the next day and I must pay R757. I missed 1 payment, how did you get to that amount. And how can you tell me my policy will lapse a day before. No prior warning. I respond with all these questions and I only get a response today, 5 days later. I am told that I missed 4 payments. HOW? I was put on a premium holiday and was told my 1st premium after the holiday will be the 1st June. That payment was successful. I need answers. I then also get a letter from OM to day that my policy is cancelled. No phone calls, no SMS's. Just emails weeks apart. I tried to call but I cant wait for someone to eventually speak to me. Been holding for 10 minutes. Id like someone to explain to me, what is going on. Today still.
