Worst service ever, paid for nothing

I app**** and paid for an upgrade on my Account . I received a message on the 23rd Feb that it is active, but up to this day we struggling to connect to it. You sent me the new WiFi line and the password, but we can't connect to it. It's almost a month now. Been transferred from pillar to post by your agents on your Watsapp helpline . And the most annoying thing is that I have to start from scratch with explaining my self with every consultant I deal with. Does your system not keep record of previous conversations.? And what kind of a service provider company does not have a contact centre, so that we call in and get things sorted. I am very disappointed and would not recommend you guys to anyone.
