Returned Item Missing

I've contacted Takealot on 17Aug18 to return my Huawei p8 lite which became faulty. They collected the item and send it back to the supplier. The supplier apparently fixed it. On 19Sep18 when I followed up with Takealot again to find out what is happening (as it has been over a month now), they said they phone has been delivered. First of all, no one from Takealot contacted us to advise the phone will be delivered, and secondly they did NOT deliver the phone to us. I'm not sure who they gave it to (if they did at all). I mean, you can't just give a parcel to anyone, without knowing who you are giving it to. Since 19Sep18 I have been struggling to get any answers from Takealot. They keep on saying they will follow up with the courier company. I mean, does it take more than a week to follow up? They also have this 21 day policy where they will refund you or credit you if you didn't receive your item back within 21 days. They have not refunded or credited me, so this policy is probably also non-existent. I am at my wits end, as I have to constantly follow up with Takealot, and I'm not getting any joy. I want answers today still. Will I get my phone? Or will I get a credit or refund? I will not lose money because of Takealot's negligence. This is not on at all!
