Joiner dates and NOW claims

When I joined Bonitas it was mid month so had to wait for new month, however I wanted to be covered from March therefore paid EFT and my debit order came off in April.....I received correspondence confirming my joiner date had been changed yet received the incorrect card in the post - long story short Bonitas kept changing my joiner date when all i was requesting was a new and correct card!!!!! Somehow via email there was confusion resulting in Bonitas giving me an extra 3 month 'probation' period - DISASTER to try resolve!!!!!! Now I sit with problems on my claims due to a system error, I called Bonitas to query the first rejection and was told that it was my first appointment confirming pregnancy and therefore the next and following claims would be paid....I submitted my 2nd claim which came back with the exact rejection code, called to query and was told system error and I have to start the WHOLE claim process again which takes 7-10 working days....I will be submitting my next maternity claim before this is even resolved - no doubt I will be facing this EXACT problem with that one too
