UBER EATS DEDUCTING ********LY

I have ordered once from Uber Eats which was a terrible experience and we never ended up getting our take aways. We have now been debited in two occasions from UBER EATS which are not our transactions. Our bank has suggested dealing directly with UBER EATS but there does not seem to be anything online offering contact details. This is ***** and I would like to take it further.
