Shocking Service

I have been waiting in excess of 2 weeks for a refund or replacement for a Nokia tablet that failed well within warranty. Despite been purchased through Takealot ,who merely send a robotic updates that saying nothing, it appears there is absolutely nothing I can do. A number of calls and emails to Takealot informing them that I depart for the UK within days has produced nothing. I cannot find a phone number to contact this seller. Be warned.
