Cell C head office service sucks

Being resident in Margate,kwa Zulu natal means we have to travel 100kms for a cell c service centre. We recently did an upgrade as well as handed my wife's phone in for repair. We received fantastic service from the branch staff, however when matters were referred to head office all service fell away. My upgrade took them 5 day's to approve causing me to have to travel back to amanzimtoti to collect the new phone. We handed my wife's phone in for repair and 2 months later still no updates despite the attempts by the branch staff to get information. Cell C really needs to sort out this disgusting service from their head office.
