Neotel's call center and service sucks

My issue goes back a year with this shoddy service from Neotel, they have no/little product knowledge...a year ago I tried registering on there website to be able to see my data balance but received an error that I can't register,i did what a normal person would do,sent emails to them and called in the call center numerous occasions with the same excuse that their I.T department is busy resolving, day after day went by and eventually it became weeks and then months,I eventually left this and kept calling in monthly to see my data balance only problem with that is they take so long on the phone and put me on hold all the time. Yesterday(04 December) was the last straw,I called in put on hold 10 minutes then the lady comes back & says there's a system problem and can't access the system and she promised to call me back and took my number down although having it on my profile! Not only is the wifi slow there customer service sucks or is just a lie as it doenst exist,I seen other complaints on this site and Neotel responding they will resolve with clients but seems same people saying it doesn't happen,dont give a response because you have to,give it cos you want to resolve client issue
