Very bad service from Homechoice

In August 2019 I ordered the following form Homechoice; Maison 5-piece duvet set x2; - Pierre Cardin Martinique 5-piece duvet set (still being processed; - Shelley 7-piece duvet set; - Nina 6-piece duvet set; - Sasha 9-piece duvet set (still being processed; - Remi duvet inner (out of stock); - Mauricia 3-piece bedcover set; - Jordan 3-piece sheet set; - Shelley 5-piece sheet set; - Liyana 3-piece sheet set; - Trisha 3-piece sheet set. The good were delivered on Wednesday the 21st of August but the following were missing; Mauricia 3 piece bed cover set, Nina 6 piece duvet set, And I only got 1 set of Maison 5 piece duvet set. Some of the goods were still being processed hence were not in the bags. I later cancelled that order because I did not receive them. 2 bags came in that Wednesday morning and only one invoice came in one of the bags which contained the Trisha sheet set. I immediately contacted Homechoice via email and phone, and one Mark Wegner responded. I told him what happened, and he said that he will get back to me. He told me that the above-mentioned sets were sent in the parcel according to their records. I asked about the missing invoice because I did not get it and he said that he will send it to me. He said to me that they will carry out the own internal investigations which he said would take 6 weeks. He also asked me to go to the police and make an affidavit and send it to Homechoice. Up to now I have not received any further information from them, although I sent them emails asking about the investigation. I am currently paying R713 per month via debit order including goods that I did not receive. No one from Homechoice has cared enough to tell me what is going on or what happened.
