I do not want this account anymore

Where do I even begin here with this, I paid Foschini, last week Thursday at the store, then they send me a message I need to pay R110.00 with the arrangement I made with them, I paid R550.00 on the Thursday, I do not remember making an arrangement about what specific amount I am going to or need to pay, I told you all via email I will make the payment, but no, this is how a person gets a bad paying record because you guys are constantly owing this and that, you are making me want nothing to do with accounts ever again, I am getting so tired with you guys just walking over me.
