Unauthorized VAS debit orders added when upgrading with Elite Mobile

Be warned against upgrading your vodacom contract with this company. They added about R330/month "value-added services" debit orders to my account without asking and without my consent after upgrading my tablet contract with them. I have phoned and told them to cancel it - I have not received confirmation yet that it has been cancelled but I am trusting that they have done so. But I feel that all other customers should be warned against upgrading with them and should rather go directly to vodacom - I definitely won't ever upgrade with them again.
