unable to pay for my claim

firstly would like to thank you for a qiuck response on my cuortesy car issue. No w my problem is budget decline my claim saying they didi not received april premium so my question is how come because there is always cash om my account on the 27thof every month asking why the change to the lasy day of a month so they say i didi say so now i asked they what makes them to collect on the 27th becuase thats what i know of the date of debit so they say as from October last year they decided to debit on the 27th since there were no funds on the 30th that where the problem started , they change the date without communicating with me then again from jamnuary they change again to the 30th so now i dont understand since there was no communication about it all i know is they debit on the 27th since all my debit went through on the 27th. and what strange is they didi debit to april reinstate the policy so now why they say they will not pay for my claim / why they reinstate is april is not covered. Now since i have a a claim they coming up withso nmany stories that was not communicated to me they just claim that they sent an sms of which i did not received it the best thing was to call me.
