Return nightmare

Takealot really should create a careline to speak to people returning items directly. I told them when I returned a phone that was network locked to vodacom I preferred a replacement that WAS NOT NETWORK LOCKED. The sim wouldn't activate or rica. I didn't like this and wanted the same phone but not locked so that my daughter can use her telkom sim. What do they do? Replace it with the exact phone that I HAVE TO GO AND COLLECT BEFORE I CAN RETURN IT AGAIN FOR A REPLACEMENT. This is an early Christmas gift that is getting later by the day! Utterly disgusted.
