WORSE GAP COVER STRATUM

I have had this insurance gap cover from 2021 and from then nobody has made an attempt to assist me. emails dont work and they havent responded but quick to run debits every month. I want all my premiums paid back to me as im tired of chasing them , worse case il be going to the OMburdsman as they have not comp**** to even reimbursing me after a certain period i was suppose to get a payback.....
