Upgrade gone wrong now I am cut off

When will you get your service correct?<br> I upgraded last year where I was mislead and given false information about your product. I have been a client for more than 10years and you have debit my account for 10 years so what has changed? and then all of a sudden you soft lock my line due to your mistake. Can this be sorted out ASAP as it is ridiculous. <br> I have been waiting for a month for a response from your call centre.<br> <br>
