Now i cant get my upgrade

<p>On the 3rd of June i made payment for my Vodacom contract at vodashop century city.For some reasons payment did not reflect on Vodacom acc which caused the blocking my account.I ran around gathering,faxing nd emailing proof of payment as i had done on time.Eventually the matter was resolved but my score was affected,and I can't get an upgrade.I have called nd emailed them but they won't resolve the matter and give me my upgrade when it was their fault that payment did not reflect in their system...What an inconvenience again???</p>
