Zip Zap device short Lifespan

Disgusted in Zip Zap mobile card machine service. Give a error and call center inform you, you need to buy a new device, the current device software is *******! As a small business owner this seemed like the perfect companion, but to just replace a device is not that easy and affordable. Perhaps due to all your "maintenance sms messages" you are *******ing your clients device's software?? I want to warn all small business owners against this short and poor lifetime of the device. Rather put your trust in a company that can give you a better product with a longer and trustworthy lifespan.
