Uber Eats / `uber one

Warning .... please be careful Uber one has been deducting R50 per month from my credit cards for the past 5 months without my approval. I have had to cancel 2 x cards because they will deduct the R50 per month from whatever card you use to pay for deliveries. I canceled my first card and they continued deductions from the 2nd card used. The contact number for customer service is not in use and there is no email address for complaints. DO NOT MAKE USE OF UBER EATS UNLESS YOU DELETE ALL YOUR CARD DETAILS AFTER EACH USE.
