Poor Customer Service from MRP H/O

I went to the MRP Home Cresta Store on the 26/09/18 and ordered the Chelsea Couch (Charcoal), it was only delivered to me on the 05/10/18(Friday) and the incorrect colour (Blue). The drivers would not take it back, coz I have to contact HO and complete the Return Form. I have sent the return form, The only response was to say "They have received the query and someone will get back to me" I have also called the HO numerous times, they asked me to take pictures and send to them, with the same response that they will get back to me. Yesterday I called at 4.50pm, I was cut off twice. Eventually I did speak to a lady. and explained for the 5th time what was the query even after giving her the Ticket Number. She said to me the they will inspect the picture for any damages, (what damages will their be if they only delivered on 05/10/2018. She promised that someone will call me this morning, I am still waiting. I even sent an email this morning again. She also mentioned that they will pick up the couch, inspect it and after 7 working days the correct couch will be delivered. Which is unacceptable because I cannot take leave to accommodate them to delivered twice.
