hellopeter not responding re potentially false posts

I notified hellopeter (via their online contact form) about potentially ********** posts that I had actually used to buy a laptop, with disastrous results. Hellopeter has not even acknowledged my query, let alone investigated.

The query was about the reviewers called Laurie V, William G, Quinn G, Josh J and Paul R, where I noted (after a very bad experience) that these accounts do nothing but regularly post positive messages about Laptop4U Cape Town, Laptop4U.co.za and Smarttech Solutions, which are all the same company (or have the same physical address and owners). William G has done one other post, at least).

I pointed out that on the 3rd of January, from 15h20, all these accounts started posting positive messages within a few minutes of each other, re one or more of the 3 'companies' (all actually the same company), that I mentioned: Carl J and Ettiene S also posted to these on the 3rd, followed by Michelle B on the 4th.

I thought that Hellopeter would be quick to respond (as they actually used to be) but they haven't even ack'ed response
