RUDE AND POOR PROBLEM SOLVING S****S FROM LEWIS GIYANI

I sent money to my little sister to laybuy me a TV stand at Lewis,I settled my payment at Lewis and they promised to deliver within 48hours like their advert."SAME DAY DELIVERY" . But then now I am still here with no delivery. I told my younger sis to go to Lewis Giyani to ask when are they going to deliver and hurray the Precious Branch Manager doesn't know and my sis called me I then told her to do the refund since they can't deliver. And then again the precious Branch manager told my sister to wait for customer to buy coz they dont have money. I called the Branch Manager to ask how long is it gonna take for them to get the customer coz sister is with her son and she might be hungry and guess what she said she is not gonna talk to me because I am shouting. And she hang up. I called Lewis customer service to get help and they said they will call me in 48hours how helpful it is. Oh did I mention that the call centre lady told me to give the store manager phone so that she can talk to her I mean really. I used my own money to buy that tv stand and now i am wasting my money on transportation because our Lewis cannot fulfill their promises. This is how they treat their customers at LEWIS GIYANI
