They really don't know how to treat their clients

I contacted Woolworth my self in the beginning of February explaining why the account was not paid in December due to the fact that the was a house *******, where they took everything including bank card I was gun pointed. In January I only worked 2 weeks and I asked them to debit my account on the 27th of February I inform them I will pay r400. Now I get a shocking call saying that I have been handover to the lawyers. What is the point of making arrangements it's not Even 3 months it's 2 months December and January. They even responded to my email acknowledging my arrangements.
