Disgraceful product support

I purchase a homequip mosquito repeller from dischem, about two weeks later the device started beeping we replaced the cartridge as we thought it might be empty, after spending R150 for the 2 cartridges the device is still beeping, I send a message to motoquip / homequip via Facebook messenger, sent an email and called, when I called I was told that a consultant would call me back, it is now almost 2 months later and I'm still sitting with a device and 2 cartridges I can't use. This is the worst after sales service or product support I have experienced and would not recommend the motoquip or homequip product to any one.
