FRUSTRATED CUSTOMER - TFG HAS ZERO CUSTOMER SERVICE

I purchased a few items on 27 Nov order no. p***, which was to be delivered to my work address. It's now 19 Dec and I am on leave. One item to this day has not been delivered. I have called several times and I email the customer services, one line shopping but the only answer I'm getting is that it's out on delivery. Last email says it will be delivered before 12 Dec. It has been out on delivery for the last 3 weeks, next week will be a month. I understand that they have a back log since Black Friday but this is definitely unacceptable service. When you call the consultants keep blaming the courier company. I think TFG should take responsibility for this service as the customer paid them for the shopping and not their courier people. I called on 11 Dec (after I spoke to 2 other consultants) to change the delivery address as I'm on leave from 15 Dec. I get an SMS today Saturday 19 Dec, saying again that my parcel is out on delivery and that I must "Please ensure that I am available at the given address" The courier calls says he confirming my address which is my work address and I say but I am not at work on Saturdays and furthermore I am on leave since 15 Dec. He was rude and spoke to me with no respect to his customers and says if I dont listen he will out the phone down on me after I was trying to tell him that I have change the details at TFG for them to deliver to my home address. He tells me that was not the arrangement and cut the call. Call the TFG call centre again spoke to Zandile who refused to connect me to a manger or escalate the matter and put me back on the call centre waiting que after I asked to speak to a manger. When the call was picked up again, it was her on the line again and I confronted her about what she did, eventually I told her the story of the courier refusing to deliver to my home. Waited 25 mins so that she can make some arrangements, still no reply and still no parcel delivered. I'm frustrated as this was supposed to be something that my daughter was supposed to take with her for Christmas holidays with her dad, but she has no jeans but a top only to wear. I cannot understand the inconvenience that TFG puts their customers and make false promises they still cant keep. Hopefully I will get what I paid for before New Year!!!
