Taxify poor customer service

I was very comfortable with using thos service as I never had any problems until a week ago. I downloaded the new app without checking that my bank account was still linked, I took my family out for the day and had three drivers, I paid cash for the two trips but when we finally went home after a long day out I took my wallet out the driver said that my card is linked to the app and that I don't need to pay. I reported this via the app but received no response and called to the offices too but no anwer. People please watch out for this as taxify will not reach out to you and its such a shame. I am very disappointed in this service as I was a regular customer. But I will use Uber in the future.
