Change of banking details for debit order

Hello Useless Altech,

Please email me a detailed explanation why you send my account to debt collecting because for the past two months I've been making EFT payments to you as a result of your incompetence. I've send you guys an email to ********** on the 2017/07/14 1:48PM telling you that I've closed the account where you're debiting from and giving you the new account but to this day I haven't had any response. Please if you can explain this to me because all your failed debit orders I paid them via EFT after receiving your SMS with the amount on it. I'm still shocked that you have guards to send me to debt collection without responding to my email regarding change of banking details or even calling me to find out why the debit orders are failing.
