Poor feedback at Takelot

What a poor shopping experienced by Takelot, ordered 40kg weights for Christmas, luckily realised before that they had sent 30kg weights, almost a R200 difference on their site, lodges a return and replacement request only to find that they do not have the selected item, yet still to this day advertising product available, ordered a replacement only to find that I must pay a heavy weight surcharge of R200, not requested the first time, so what is the difference 40kg no delivery fee, 30kg R200 delivery, so for a lighter weight I must still pay in, complained on their website, only to receive a generic, my account has been credited, even after them closing my ticket and me opening a new one with the same query, same generic response, even though my argument is that the first delivery was done free as advertised, incorrect goods delivered so I had to request a change, costing me money to drop off goods at their pick up point, and now goods that I should have had for Christmas I must pay monies in, disgusting that no one does the effort to investigate the matter and see the logic that they incorrectly delivered the wrong product and the onus should be on them to replace at no delivery fee at least, why must I pay more for Takelots mistake.
