weFix Service is worrying me.

weFix - Gateway, Umhlanga, Durban Cellphone LG G6 Took in today (10Feb18) as it was not charging and they replaced the battery. Collected after 1.5hrs (11am) and charge was 40%. When I got home, put it up for charging for 6hrs as noted by weFix, The phone did not charge.

Took the LG G6 back immediately (12.00 noon). weFix counter rep. said possible causes: 1. Charing Dock has corrosion. 2. Possible Board Issue (He checked the operation when I collected, all OK!?????????)

This has put me in doubt of their Customer Care and professional handling of customer service requirements. I am now wary of weFix andI do not think I will risk using them again.
