Bad service

I've had issues with them and their payment links for the last couple of months, I asked if I EFT could be done I was bank details via Whatsapp by Tazlyn my bank wasn't accepting the details when I advised of the same, I was told "the account number cannot be invalid" with no alternative option. My recent issue is; my account was being by them debited by them, when there was sufficient funds available by they were unable to debit the account, everytime they tried it cost me R7.00, However due to me being frustrated , i contact my bank and asked about why i was unable to work to a standard bank account, my bank advised to use the universal branch instead, which so a payment of R850.00 was made to Rentoza, my subscription is R899.00 but account was short due to the debit orders being unsuccessful. I then sent proof of payment to Rentoza and advising them of my short payment and that would paid with the next payment. please see response below; Lehlohonolo Tsolo (Rentoza) 07 Jul 2022, 12:51 SAST Dear Debtors Thank you for alerting us about the situation.
