Poor Customer Service from Mr Price Home

I ordered blinds and curtains online from Mr Price Home on Monday, the 14th of September. On Saturday, the 19th Of September I only received the blinds of which one is faulty (by the way). Since Monday, the 21st of September I have been complaining to customer service and I have informed them that I never received the curtains after they changed both orders to delivered. The person who supposedly signed for the package doesn't even exist and I have mentioned this to them as well. After sending 3 emails, a facebook message, calling them and chatting to an online consultant, only 2 of the emails were rep**** on and you could clearly see that the person on the other side of the computer did not read the complaint to the end as if though they just wanted to reply and get it over with. I have requested proof of the so called signature on the second package and haven't received any feedback whatsoever. I am very unimpressed as I have been a loyal customer of their online shop for more than a year now. I have not been given peace of mind until date. This is unacceptable. The curtains is worth over R300 and I will keep complaining until I receive the service that is so easily promised
