Why am I paying for weFix's school fees?

Took my iPad to weFix Melrose Arch to rectify a booting/login issue. I needed to collect and return the device from/to the store numerous occasions over the next few weeks at my expense and time, as their "fix" changed nothing. Eventually the store returned the device to me with the identical problem that I brought it to them with, told me to take it to Apple, yet charged me R250 for their efforts. My complaints fell on deaf ears with the manager, Peter. He conveniently forgot about my issue and failed to return my numerous calls to address this issue with him. I ended up taking the device to the Apple store, who rectified the issue in 5 min without charge. Why am I paying for weFix's school fees?
