Not impressed in the slightest by RCS and MBD Inc

So I took out a PS4 under Game Finance (big mistake but whatever), funded by RCS, apart from them NOT debiting when on the date I specified MULTIPLE times, they decided to debit much later when funds were unavailable, and instead of contacting me they resorted to silence and insisted on debiting at a late date, despite my complaints I received no contact from them, except SMSes asking me to contact numbers that do not go through... (right!?) The ONLY call I ever got was from a girl from MBD (after all that trouble I'm handed over already, nice) informing me of my outstanding payments and how much I need to pay to get back on track with the account. Now I understand it was not her fault that all this happened but I flat out refused to pay amounts that should have been deducted on time on my account, I mean what is the purpose of debit orders? So I allowed a debit to be done ONLY to the amount I was meant to pay monthly. That went okay for a while until I struggled to pay a few months ago... Life happens, I got calls I ignored, SMSes I deleted, there was not much I could do at the time anyway. Now I'm at a position where an proper arrangement can be made and I need it made soonest, I went through to their site and found an email address *** and messaged them immediately, explaining that unfortunately my new line of work does not allow me to attend to calls during working hours and I knock off quite late. You would think someone would get back to you. It's been weeks. As much as I blame no one for the position I landed in but it is NOT my job to follow them around and have them communicate with me on THEIR terms. What do they have an email address for kanti!? This is the only time I have to make such an arrangement and sort this mess out so they can be off my nuts for good. I WILL NOT ANSWER MY PHONE AT WORK as it is not allowed. And I will not allow my credit to be dragged in the mud over a collector's incompetence. I am trying to fix a mess that was caused by RCS' incompetence and hurdled by MBD's incompetence too. I have sent them an email and would like this collection to be removed from my records and I'd like this IN WRITING. I will gladly make an arrangement to pay my account and allow a sufficient debit order to be processed then and ONLY then. I have emailed both companies and have received no response. And I will continue to use such platforms until I receive an EMAIL attending to my queries. I am a client, whether owing or otherwise, it is the company's duty to ensure they get back to me, otherwise I will find an alternative because I refuse to have this over my head any longer.
