Takealot delivery to wrong address and puts the blame on me

I am a loyal customer that has been buying alot of items from you guys for a long time. Actually me and my wife are both Loyal customers. We purchased a gaming headset which we found to be faulty. When we received the item it was delivered to our home in Piet retief, we then went away for a week to midrand jhb. This is when we found out item was faulty, we arranged for collection in midrand which was not possible, so they collected item from our home address the following week. Now my problem is they have started to send my exchange item to the address item. Which I did not request. I have called you guys several times to correct the issue. I have just received a email stating that you guys cannot do anything now!!!! This is not my fault. I received the email from Tenika Christians. They make it sound as if it was my fault who entered the incorrect address. This is the first time I have received such terrible service from you guys and are really dissatisfied. Please contact me to check my accounts and you will see that I am a really good customer who supports you alot and this is what I get for it.
