Postponement of delivery

I bought a couch to be delivered. I was told in store it would be delivered today and that they would let me know what time. My mother took leave from work to be at home to receive the delivery today. This morning the warehouse delivery phoned my mother to let me know that I did not answer their calls yesterday and they even sent an sms. This is a blatant lie as I did not receive any correspondence from them yesterday. Why would they phone my mother this morning and not phone me? And even more so why did they not phone my mother yesterday if they had her number and could not get hold of me yesterday? <br> After a whole argument this morning they tried to make arrangements to get it delivered today as was arranged, just to inform me that the couch was not even ready to be delivered today due to the fact that the scratch guard was not yet done.<br> <br> This is totally unacceptable service. My mother wasted a day leave and now I have to arrange for tomorrow's delivery as someone did not do their job. This is utterly disappointing.
