I paid for groceries on 9/12/19. Groceries were delivered and I saw the payment in my credit card app. 3 days ago I see an email saying the payment had not been taken due to issue with MasterCard and they would now take payment. This took me over limit on my credit card. Called, emailed and spoke to manager, Ocado do not care at all that this will affect my credit file. All I wanted was to pay them with another card and for them to reimburse the payment. Computer says no, speak to MasterCard. Worst customer service possible, if I receive an over limit charge or marker on my file I will be making a formal complaint. Avoid this company, customers do not matter.
