Bad service!!!

I called in last month to change my banking details and I was informed the system is down I have to call in again and I did and the system was still slow so the sent me their banking details to deposit the instalment and I confirmed with them the amount and they informed me no its R200 more due to subscription that's costing 7.99 a day, I asked the consultant to cancel the subscription I am not aware of it and he said he couldn't and will log a case for me and they took 2 weeks to get back to me and I missed 2 calls from them, I then called in and I was informed the case has been closed and consultant will send a request that I get called and up to this day they haven't called. I then decided to let it go and just pay the R200 and I did and to my surprise it was now R400 extra and was debited from my new bank account on the 25th and I didn't have money then and eventually they got money the following day, my normal debit date is on the end of every months( I don't know why they changed it) I called in a few minutes ago to find out what is going on and I was informed the system is slow I must call in later!! do these people even care?? Your service is disgusting!!
