Bad software rude staff members

Last year just before the festive season we happened to be at Westgate mall and we were approached by a gentleman called Thabo just by the food court who advised they were promoting the methemagics software we advised the gentleman that we were in a hurry as we just came to get food the guy said it will only take a min and we waited n gave him the chance to explain he sold us the software,we advised him that we had a Android chrome book and he said no problem the software runs on Android,we also asked if there was an cancellation or cooling off period and they said 14 days after software has been activated we paid 250 on the spot and got the package,to our surprise when we got home software was not compatible,I also went on google play to check if there was an app and found no app I then contacted support,spoke to a Thato I think n he advised that we needed to take the laptop to Jabulani mall so that they can have a look and it was just on the 19th of dec we were already going away and I asked the gentleman why are they unable to send me the files via email then I just install they said they will send a link and I did receive the link for Dropbox and I downloaded then and when I wanted to install the files dnt want to run as they were in unsupported format and wanted me to format the laptop and we can’t just format as we have sensitive data on the machine and while I was still waiting for a solution from tech department then I got a debit order which I immediately reversed as we have not activated the software,then I started getting calls and I keep explaining the same thing and no resolution, and the last agent whom I spoke to last week and today around 10am is very very rude and bad for business,I dnt understand what kind of Micky mouse operation is Lion Minds running there as clearly there is no notes on their system and this affects the end user as this guy was the same guy I spoke to last week and when I humbly asked to speak to management he refused as if he owns the company and he almost caused a heart attack to my wife as when he called the day before we had just lost her brothers father so she was in bad state n the rudeness of the agent dnt help as she ended up hanging up and the guy called back and I took the call tying to resolve the matter but his arrogance was too much I also ended up hanging up and he kept of threatening me that he will keep calling and harassing us as I dnt want to tell him why I returned the debit order after I had explained on numerous times to him and the tech staff ,our legal team is dealing with this as when I asked him why we are billed when the software is not activated and he said that is the technical part of the problem he is dealing with the administration part ! I mean what nonsense is that really this guy should not be dealing with clients he has no idea about client solutions
