Take A Lot taking a lot of time to collect my return

RE : RRN-948c-fd17 (my return/exchange ref number) I purchased a WiFi router that was delivered sooner than the provided date which was great, as Take-A-Lot often does that. I realized I ordered the wrong model and logged a return / exchange request the same night I received it. I got a ref RRN-948c-fd17 and a confirmation email that a driver will come pick it up the next day Tues 2 June 2020. No one came. I went onto their website to log a service request for the failed pick-up the same night and received an email from Keegan Pillay on Fri 5 June 2020 that he will investigate and get back to me. Keegan did get back to me Mon 8 June 2020 advising that the collection of my return will take place 09 June 2020 by 17:00 pm.

It is now 19:42 pm and a take a lot box is still in my kitchen waiting to be picked up. And I have clearly stated that I don't want to return this router for a refund but an exchange so I can pay the R1000 difference so I can have the router I want.

I currently have two orders on the way, already paid for but not shipped and I wish I had waited till this is resolved cause I'm not even sure any more if I am going to ever receive them.

Extremely disappointed and angry customer, Zam
