UNHAPPY CLIENT(*****)

Mrs.Greef Good day I just want to know what I should do This Lewis store from Parow continuing contacting me (pensioner) for money i don't have,where i already paid the the R18000 for the fridge as agreed in store

Now that she's finally done with the 18000 they have a nerve to contact her now to tell me that was not the amount of the fridge they still want me to pay 8000 which I don't have I'm a pensioner They manager was at my place to ask me just to pay the R674 and we ask them to put it on black Nd white(on paper) the manager said he will the following day and never did Today they phone to tell me the manager did his own thing,he explained wrong What are they up to?
