Wesbank Call Centre Service - Bad

To whom it may concern, I'm currently in arrears with my Vehicle and contacted Wesbank to make an arrangement on this account. The arrangement they want me to make is very high and I cannot afford it. After I have explained that paying a full installment and catching up on the arrear amount set by Wesbank is not achievable. I'm more than willing to pay an additional amount for the arrears but it must be affordable. The lady at Wesbank Pearl (Call Centre) was rude and kept on saying that I must pay 70% of the arrears amount, after I already asked her to make an arrangement. She does not listen to what I'm telling her, and assume that this is what needs to be paid, and it must be paid in 20 minutes time! I'm very shocked about the service, because as per Mr Rudolf Mahoney he said in case where a client is facing a short-term financial squeeze, one can make an arrangement with Wesbank to pay a reduced installment for a couple of months and once expenses fall back in line the client can repay the arrears that hat accumulated over an agreed number of months. Why will this be said and as per this lady Pearl there is no arrangement that can be put together? I would like Wesbank to contact me (Senior Management) if possible to advise what arrangement can be made on this account.
