Terrible Customer Service

So I bought a mini max vacuum machine from these guys a few months ago thinking that I could use it for smaller jobs in the house. Little did I know that this was never going to happened. So apparently, this machine has a cut off switch if it used for too long. I supposed this is to protect the small motor. However, this one cuts off literally every 3 to 5 mins. We were not even able to vacuum one small rug in our lounge without the machine going off. So I took the machine and requested assistance as this was not acceptable. I requested a repair, replacement or refund. However, after 2 week the store called and said that I need to Pay R41 to replace the filter and the machine will work. A week later I collected the machine only to find he same problem. Again I went in to report the problem. This time I was told that head office will contact me. It has now been over a month and I still have,'t received nay feedback from them. These guys are really difficult to work with and I suggest people stay away from them. It has been over 2 months now, I don't have a machine and neither do I have a solution. So my advise is stay away from these guys. They are clever with their advertising but their product don't work as well as advertised.
