Bad responce and poor communication

I have registered with home choice so i can place orders on the 27 and 28th december 2017. I uploaded required documents on through their online portal,whatsapp and emails privided. Iv been doing follow ups as to why am i not getting any responce from them but all i get is they did not receive any required documents. Ive done the process more than 5 times now of uploading the docs on all given channels that i can use..but still they telling me they did not receive. To make it worse is the whatsapp they provided..did confirm that they received my documents but im still surprised why they are not captured. This is just not professional from this retail outlet and no one really has answers.im really disapointed..☹☹☹
