Homechoice bad service

My mother,77,been by homechoice for years,buying up to R8000-R10000. Bought a lounge suite covers. One was damaged and she send ir back. Then our problems started. Everyone of our family tried calling with her present. They demanded full amount,even started charging her for the free gift they gave. Two months ago she owed almost a thousand rand. Now they billed her R2000. No replacement of the R1200 cover and nobody to call or email. Now we taking her next week to see an attorney. Two and a half years ago we spend over a month driving up and down getting a replacement for another product. Forcing now my mother not ever to buy by them. Everytime we give her the phone to identify her,they come up saying she is giving the wrong phone number and yet,when they call for sale,they call her number she had now for years.
