Vodacom upgrade dept

i upgraded last week, vodacom upgraded the incorrect number. i have been trying for 4 days to get my account sorted out. my phone contract was changed to a new contract R200 more expensive than the one i had. i need this changed back to the original contract i had and the upgrade has to be moved to the correct number. being sent to pillar and post nothing has been done up to now. spoke to the online dept and i was told there is NO telephone number to contact for this dept who should sort this out. this is totally ridiculous, just another money making ****. obviously i have to use my phone to this means extra money to vodacom.
