So disappointed at the help center

SO DISAPPOINTING, I never had any issues with Webafrica, I felt like its one of the best ISP companies until recently, the Fibre keeps going off for 5-16 min now and then and I have tried contacting them via whats app, first-person took almost 4 hours to reply me and told me they had reset the line and should be fine, 3 days later it happened again and chat with them on whats app, they have logged a ticket but the description for it is totally wrong and its been almost a week and still don't have any reply, today the third person helped me and say they are investigating it????

and as well I recently did an upgrade and I am also not getting the speed I am paying for, its supposed to be 1000 MB down and 400 MB up, and I am still at my old speed and they are charging more.

this is so disappointing, and as well as one advice to WebAfrica, GET BACK YOUR CALL CENTER !!! its so frustrating when the internet is off we have no way to contact you GUYS, and even if we do with whats app it TAKES HOURS
