***** tracking debit order

I joined discovery in January how ever they cancel my policy because they did not get funds on a date we did not agreed upon for a debit order to go through. I was in contact with them for a query but I never got any feedback or a solution towards my query. So they tried to deduct using another reference I'm not pleased with that as they failed to get back to me now they tried to take my money without my query being resolved. What they are trying to do is ***** because they did not re-instate any payments plan with me
