Quick to loan, BAD service, Can not change debit order date

Needed to change debit order date. 1st call went unanswered. 2nd call I was placed on hold for 20 minutes. 3rd call - call agent was sighing so much on the call and so not interested in assisting. But provided her all the details to change my debit order date - felt like an eternity, repeating information. Asked to speak with line manager - who is also very unwilling and totally not intrested to assist. Lodged an official complaint on their website - just to be informed that ALL my time was wasted cause now I still have to provide Lecrecia Arendse with my details YET again so that my initial request can be done?

I have been with them for years - NEVER have I been treated with such disrespect and total "you-just-another-number" service. WILL NEVER recommend or refer anybody to them again.
