Poor communication and service

I am actually at a loss of words regarding the poor communication and service I have received. I ordered 3 items (one of each) - doubles of of two of the products were delivered and one product was left out completely. I communicated this to Takealot - they said I should send back the doubles and they will then send the product that I hadn't received. I send it back... Then I followed up... They then created a collection (for the product I haven't received). I then communicated with them that it can't be collected, as I never received it, they said this will be escalated. The courier still arrived to collect the package. I explained the whole situation to him, he stated he will sort it out. Now I received a message that they couldn't get hold of me so they will reschedule. I still haven't received the product, or a refund.
