Does Jet respond to their online queries?

Earlier this year I had an issue with Jet and logged it on their website and a 3rd party website dealing with their queries,no feedback received until I logged it here after 2 weeks. Again I have an issue and logged it a week ago on their website no response received...does it even work?I therefore called in their call center as I require a refund for items that I was incorrectly billed for but I think the call center agent(Nqobile from Edcon ***) did not understand my issue as she wants me to cart those goods back the store(not only is the ques hectically long) it was purchased at and return it,I don't want to return it I want a refund for the overcharge.it seems Jet likes the attention even if its bad,for a R30 refund is it worth my time,effort and money?Lucky I still have the items because I was told picture evidence is not enough,imagine if it was used I must be out of pocket because of their incompetence its my phone bill, my time on the internet, my time trying to resolve there mess up now I must drive 40km and take the goods back to a store and wait 30 mins the que for R30 refund.
