Unable to assist

It is with great sadness that I have to resort by writing this, since Standard bank are this cruel. I have been retrenched from my work since April 2014,since then I have been having Ups and down repaying my bond, but I try by all means to pay it. My bond is now R18k in arrears and my normal bond payment per month is around R3300, because I'm in arrears I decided that I'll pay at least R4000 each month when ever I can at least I'll be paying extra to pay arrears. But now Standard bank decided to give orders to the LGR Attorneys to take my house for auction unless I pay 50% of the arrears plus the bond installment, I don't know where I'll get R12 300 from because I'm retrenched I don't work They don't even want to make an arrangement, the lady fro LGR attorneys told me that even if I pay my monthly installment plus the extra towards paying off the arrears I'm still going to lose my house if don't pay the 50% pus the monthly installment. I am trying to get employment, from 2014 till now I have been paying my bond from peace jobs, Why do I have to lose my home even though I'm trying by all means to pay my monthly installment?
