PATHETIC SERVICE!!!!

Such pathetic service, I upgraded my line from a 10MBPS to a 50 MBPS, they were quick to change it on my profile but FORGOT the important thing to actually UPGRADE the line. It showed that my line was upgraded on the 12/03/21 on my profile but no one can tell me why the actual line is still on 10. I have been sent from pillar to post, technical is telling me that it is a sales related query and sales is telling me it is a technical query. Don't even get me started on the fact that my e-mails are being ignored and my tickets being closed. I have wasted so much airtime calling them, no one ever bothers to actually bother calling you back. They scheduled a call for today at 17:00, at 17:20pm I called and held on for 22 minutes and no one ever picked up. Oh did I mention they were quick to send me an invoice for the pro-rata I am going to pay BUT NO LINE HAS ACTUALLY BEEN UPGRADED!!!!!!
