Nonsense bad customer service

They sent me an sms stating that "if you wish to be debited on the 15th please click on the link" which was obviously to give consent for them to debit on the 15th. I didn't fill it in because I don't wish for that to happen. They made the assumption that every employer pays on the 15th and without consulting me they took the decision to lock my phone, you can't even contact them via phone and they don't respond to emails when you query the matter. What's annoying is that a person is not an idiot when they don't fill in the form it means they know that their chosen debit date is cool. They then decided to lock my phone as we speak I can't access my phone because they locked it how when my debit date is 9 days later how? This is poor customer service from their service desk down to the CEO of that company because if they had proper customer service mandate their employees wouldn't be doing such nonsense. That time their offices only open on Monday so my phone will be locked till then? Fir that I'm going to write reviews with multiple email addresses till their rating goes to 0 because this is uncalled for dis kaak
