DEBIT ORDER COMPLAINT AND FEES

6/7 later after a struggle to resolve my issues with defective products, the store managed to resolve the matter, however, I would like to express my repulsion on the fact that my debit order is still not being handled well, I made an arrangement that the debit goes off last day of the month, however today I get a message saying the debit failed, this is after I [ on several occassions] told them debit should run last day but yet they are not getting this right. My bank charges me R30 for failed debits, and I am being harassed by the Roodepoort branch with calls and messages, now you will pay for my bank charges, stop harassing me, and run the debit as per our agreement LAST DAY OF THE MONTH. I AM EXPECTING A CALL TO TELL ME THAT THIS WILL NOT HAPPEN AGAIN, THAT MY CHARGES WILL BE PAID I WILL NOT BE HARRASED.
