Kaak customer service and uncalled for treatment of customers

They debited my monthly subscription fee on Sunday yet today i wake up to my phone locked and what annoys me is that they are not doing this for the first time or the second time its starting to become a habit. I doubt these people even check with the finance department if payment has been made, because they dont even ask you as the client to send proof of payment to confirm that payment has been made they just become ****s and lock your phone then you CANT EVEN REACH THEM VIA A CELLPHONE LINE AND THEY DONT RESPOND TO EMAILS ITS SO ANNOYING. They must just tell us if they no longer want us as their clients instead if being ****e tbh cause this is bull****
