Bad Service, Dissatisfactory service

I am very dissapointed from the service im recieving from both reputable companies that is Edgars Mall of Africa in Midrand and Forever New Mall of Africa . I have bought a coat from Mall of Africa Forver new on the 26th August 2023 in store and i have been quering with Forever New customer care (Cherylene) Edgars namely with (Lerato) and manager Mpho at Forever New Mall of Africa. The coat has unbearible fluff (lint) upon communicating my concerns since June 2024 i was asked to get the code of the coat ,Mpho at forever new maganed to get the code for the coat. I am now told I will only be given R795.00 whereas the coats value is R1 799.00 what must I do with the R795. A number of times i have told them i do not want money from them but a replacement of the coat . When I chose to buy from Forever New I chose them for quality but when such happens from their product where am i to take it. Edgars is sending me from pillar to post for a copy of invoice ...Where do they keep their archives?? Can management attend to this ASAP before you run out of stock again
