Bad service by hollard insurance

I had a funeral cover with hollard for more than 7 years paying them with no problem, the problem started when my premium increased by amost 30% and I queried that massive increase and the response was not satisfactory and I ended up excepting but to my suprise I received a message that they didn't receive my premiums for two months and I called them and they say someone deleted my account number that is why they couldn't debit my account for 2 months now I have to pay 3 months premiums in cash to their account of which is more than 1000 and I don't have that money in my possession or else I loose my policy it is very frustrating, what if something happened they wouldn't pay out because of that and it is difficult to get hold of them because I waited for longer time to be connected to an agent I don't know if they treat all their clients or it is just me I feel like looking for a better insurance company I feel betrayed and ****med
