Take alot bad service

I paid for a Kingsize Mattress, base and headboard on the black Friday sale at take a lot. They delivered on the 7th of Dec, a single base with the king size headboard and king size mattress. I didn't want to accept but they said they cannot take it back, I need to accept and log a return. I even went to the Parkview branch now in January, I still cannot get Takealot to refund me the balance at least for the difference in price for the single bed base. I paid R5280 for the King base and received a single base, I am willing to keep the single but want a credit for the balance then I will buy somewhere else another base. I was s regular customer at take a lot, and in the past returned stuff and was credited if it was wrong, but this time no one at take a lot wants to help and at Parkview they just give a number *** that you cannot get hold of anyone. I had back surgery and still cannot use the mattress without a base, I should have just bought it somewhere else. Order number *** This was my last order at take a lot, definitely not so 'convenient' if you pay R6000 for s single bed base you didn't order and cannot use the bed you paid for.
