Upgrading fee of R 1000??? (migration penalty)

This is the first time in history that I am hearing about a penalty fee when you upgrade to a higher package???<br> This is ridiculous!<br> Due to your mismanagement on my account and data I had to upgrade from a 50 gig to a 100 gig and then again buy a 20 gig once off data package, one day after I bought the once off package my data was finished and your systems said that we are out of data, due to this fact and your mismanagement we lost 2 days of production time! And lost an income for 2 days due to the fact that our company works on-line. <br> <br> I have been with iburst for many years and have never finished a 20 gig data bundle and all of a sudden since I am with Telkom we are using over 100 gigs of data and there is no record of where the data went. This is seriously ridiculous! I urge you to debit the Migration penalty fee as well as the once off data bundle of 20 gig that we had bought and could not use, if our account and data is not sorted out before the end of next week I have no choice but to cancel my contract!
