False Contract Upgrades done by Vodacom

Vodacom Business Unit is extremely dismal and disappointing. As a business we hoped to have swift and correct changes on our contracts, but Vodacom does the opposite. 7 of our contract lines were to be upgraded to a more suitable package to accommodate our increased usage in February, we believed this was done because Povashnee Moodley (sales outbound) had confirmed the changes were made. Upon querying that the package did not seem to be activated we were told that Ms. Moodley no longer worked at Vodacom by other employees named Lulama and Leon, but in recent light she does still work at Vodacom but has not responded to any mails sent to her. This however is not my gripe. Vodacom has proven ********* and confused as we are currently paying for usage that should have been covered by the upgrade we requested months ago which apparently no one at Vodacom is aware of anymore even though there is an email trail as evidence. When this not so shockingly poor business unit was confronted no one can provide a solution, and the contracts have still not been upgraded hence putting me in a position where I must nag Mr Leon Jettoo for a response on an investigation he promises to conduct but i have yet to see evidence of.
