Contract is in a mess

Long story short I went for 2 upgrades they loaded it onto 2 different accounts. When I went into the branch to transfer it to 1 as it was there error I was told that I will need to pay r150 then need to do the full assessment again. They call centre is unable to help as it is not there problem. Then on my contract they have increased the amounts according to the new contract but I have not received my airtime sums or internet bundles have been a customer of there's for over 10 years but this will be my last interaction<br>
