Shocking Lack of Service with issue with return and courier service collecting!

Honestly disgusted with the service I have received. I have returned two different items but from the same order. they confirmed via SMS the items would both be collected on the same day. Their courier guy arrived and said he was collecting, when asked he said he was collecting ****IO BLACK, all the items being returned were of the ****IO brand and all BLACK. we advised this to him and he happily took all the items. later in the day another courier guy arrived and said he was collecting as well. We advise to him the first courier had take both sets of items. I contacted TAKEALOT on social media as this is the only way to contact them and advise of this and said that all items were returned to the first courier as he did not advise he was only collecting the one set of items and both were scheduled for the same day. To date I have received ZERO feedback on this and keep getting told "the matter is being escalated" and they refuse to confirm this on email and refuse to give me an email to contact somebody at TAKEALOT. They now are just ignoring my messages! Their lack of care and unprofessional assistance in refusing to provide an email or any assistance to lay a complaint! This is extremely disgusting service. I have been buying from TAKEALOT for years and have multiple returns returned. Even when I received extra items I did not order I did the right thing and notified Takealot and assisted with the item being returned. This honestly should not take so long! This will honestly make me thing twice about ordering from Takealot again! The return process is extremely poor! This week alone a had another issue where I had to return a defected item and the courier arrived and could not give the return number as he said his phone was flat. We eventually had to charge his phone as I refused to give him anything until he could confirm the number so I do not have the same issue that I am now battling to resolve. Clearly TAKEALOT do not care about their customers or customer service! Really what is a fair amount of time to expect some sort of feedback on a matter? As I think A WEEK is extremely poor! especially when this issue is the couriers fault. He should only collect items he is scheduled to collect if they are going to collect the items separately.
