Takealot failed return without explanation

I recently purchased a robotic vacuum from takealot.com It worked fine for a few weeks and then suddenly I found it at the bottom of my swimming pool. I logged the unit as a return with takealot who simply rejected the return and sent it back to me. I queried why the return was not being accepted but no one had the decency to answer my questions. There is no number you can call and the people refuse to answer emails you send asking them questions they can't answer. They simply gloss over the email and send their terms and conditions.

I told them on many occasions, the vacuum left the safe zone in my house and wandered onto my pool deck. This was not my failing but that of the units. I also told them, the unit failed at detecting the edge of the pool (like it should with stairs) and therefore fell in. Again, not my failing. Takealot simply sent the unit back to me and didn't answer my emails.

Takealot used to be great. If you had a query, they would respond and give attention. It seems now that they are established in the market, they don't care about customer service anymore.
