Uber Eats is *****ing from my bank account!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I have been trying for days now to get Uber Eats to cancel my account with them because they have been deducting a R50 for the eats pass. I asked them this a month ago already and yet again they deducted from my bank account another R50 FOR A SERVICE THAT I CANT USE because my cell number changed and when I try to logg in the verification code gets sent to my old number. I even complained on Facebook but the private message they keep on sending is for me to give them my old cell number and email address. I thin I sent it to them about3 times...then their reply is "Please send us your old cell number and email address for the account" Like What the hell! I sent it already!!! I think they are ******! Not sure what to do about this because they dont even have a customer care contact number I can contact them on to sort out this. GET BACK TO ME UBER EATS!
