Horrible Customer Service!!!

So I bought a couch from Lewis Secunda in December, late February 1 side of the couch got broken in the middle so I went to them and informed them of this and they said the couch will be collected for repairs so a week later the delivery guys came and picked up the wrong side of the couch and left the broken side in the house as no-one was home so they kept calling me at work to inform me that they saw nothing wrong and I advised them that they collected the wrong side! This was very early in March so they said they no longer have transport to collect the broken side and the other side is still with them ever since... So last week I got fed up and called their Head Office this was last week Thursday 30th of May to inform them of the battle I have been having with the store for 2 months now and they said they would get back to me on Friday the 31st of May and today it's 8 days later! Friday the 7th and still nobody has called me to say anything! This is the type of customer service I received from Lewis Furniture I am making full payments for a broken half of the couch!!!
