Breach of contract and Consumer Protection Act

I've been querying my account through the call center since November. I asked to be on Top Up in October and was told it will be effective on the 1st of November. I called early in November to confirm that I am on Top Up and was told that I was migrated. Half way through the month, I hadn't received a notification to Top Up. I called the call center and was advised that my account was still an open line and not Top Up. I asked for this to be sorted as I confirmed that I was on Top Up. I was told that the billing dept will sort it out in 7 - 14 days. Those days have come and gone. I've queried this three times after since 4 December 2015.<br> <br> Please can my account be sorted. All costs from 20 November, i will be liable for since that is the date I was told that the migration failed. AND can my account be changed to Top Up. I don't want an open line. <br> <br> Altech, I actually want to cancel my contract due to the stress and frustration this query has given me. I don't want to deal with such poor customer service and the call center agents dropping my calls.
