Ai mweb, not again

First of all, they ask you to enter your ID, cell number or account number followed by #, it never works, it stays in a loop and askes the same thing again or it only picks up half what you have entered. I called two weeks back because I noticed on my statement I'm begin charged like R270 for a rica delivery fee or something like that. Told the lady I upgraded and did not receive a new sim or any delivery. She said she will cancel it and take it off my bill. Well today my debit order went off and I was charged for it. Called again, after explaining everything and being verified I was asked to hold, after a few minutes without any warning I was transferred to sales. Had to explain everything again and be verified again.. Then the guy said I must chat with billing and wanted to transfer me back to billing just to explain everything again and be verified again.. I do not have time to chat to mweb for a hour, kindly contact me to resolve the issue
