Useless process of return with a laptop. Shocking service.

I used to love this company and used it a lot. Until I bought a laptop which died after 7 months or so. It started well with the collection made, and communications to tell me how it was going (went to the Lenovo lab as it was beyond Takealot's 6m warranty). It took almost 2 months but I was apologised to, and reassured it will be coming back soon. On 26 Nov I received an email to advise it would be coming within 2-3 working days. Nothing came in. From that moment on I have been emailing, phoning, inquiring online, speaking to sympathetic agents - but the bottom line is - NO laptop. NO follow up once they accept I have NOT received it yet. I am sure by now it must have been lost somewhere - but where is the follow up, owning up to the fact it is now unknown where the laptop is and any resolution for me, having paid for it and waited for so long? It is mind boggling.
