Really furious and worst service provider ever

I recently ordered curtains online from Homechoice which have been delivered and when I checked they where not what I wanted exactly so I sent 3 smses to be contacted and never was as time went by i call them and was placed on hold till i hanged up. They then decided to call asking if i had received the package and reminding me of the debit date, i then inform the consultant that I was not happy with the product and that I wanted to exchange it for something more relevant to me.<br> she then said she would transfer me to someone who would confirm the return and pick up of the curtains. I was then called by someone else who now told me I had to personally post it back to them, paying for whole process. This is unacceptable and now they call me everyday harassing. This has to be one of the worst service ever. I honest dont think they care much about customer satisfaction.
