lewis attitude towards non account holder

I have no account at lewis my flatmate does . he made payment arrangement s on Saturday unfortunately he could not make it to their store . as he worked Saturday and Sunday. The Sunday I know he attempted to contact the store of which there was no answer. Sunday around 10 am . they came knocking on the door threatening me which I remind you I have no contact with lewis . screaming in a block of flats which I live in about how I owe them their money and if I don't give their money they will start carrying out the stuff . the lady was going on for a r150 which was short of the payment he had made the previous Saturday. I told her I didn't have the money for her I did not have any money on me also told me that she's been awake at 5 am for people like me who don't pay their accounts. She told me I am playing around. I am running away and threatened me with lawyers I told her he tried to call .she then said he is my husband when I corrected the relationship we have she the rep**** with whatever the bladdy hell he is to you. I phoned my flatmate and she was screaming over my voice to him. All my neighbours came to see this. I will never open an account there if dis is how they treat peop
