TakeAlot Services Not As Good As Before

I am a frequent buyer on TakeALot and have never been disappointed with their services until recently. I had ordered an item from their website and was extremely excited as its something I wanted for a while now. However, when they were supposed to deliver on 6 April I was notified that my delivery will only take place on 9 April 2018. I had called in to ask if the delivery address could be changed as i was not at work on 9 April. I got told and sent an email confirmation that this was amended as per my instruction. On 9 April, i got a call from the courier to say they are at my work address. This resulted in me having to find someone to sign on my behalf (which was very inconvenient for me and the person that had to sign). However, I got my item and it was in an unsealed box. I had gone back to my order and noticed it was not an unsealed / openbox purchase. I had queried this with takealot and asked for a reason as to why and got an apology instead of the reason. However, I was not happy and requested a return. I received the confirmation that they would collect it from me on 16 April before 12h00. Again, I called in yesterday morning to notify them i wont be available and asked for them to reschedule to be collected from my residential address on 17 April 2018. The consultant had confirmed he change. This morning the courier calls me they are again at my work address. I had asked for him to leave as i am not there. I called takealot again and had expressed my frustration. The consultant notified me that they are not allowed/able to change the address and he will have to collect it from my work address when i am in again. So, I would like to express my disappointment in the lack of service i received from the day this item was out on delivery. None of the consultants before had confirmed that they are not allowed to amend the address. I had requested for a supervisor to contact me at 8h56 and till now NOTHING. I would appreciate that my matter is addressed as a matter of urgency because I had ordered another item for my son from takealot and having such a terrible experience with this order, I hope and pray that TAKEALOT does not mess this current order up as well. You guys used to be one of the best online websites but i am now doubting that phrase. Thank you
