(Telecompaper) South Africa operator Telkom and Oger Telecom have ended all discussions on the potential purchase of Cell C by Telkom. In a statement, Telkom said through its engagement with Oger Telecom, it became clear that there was a difference of opinion on the valuation of Cell C. As no agreement has been reached, Telkom and Oger Telecom agreed to end all discussions. Telkom confirmed just over a week ago it was in talks to buy the mobile operator. Earlier reports suggested that Oger had valued Cell C at as much as ZAR 22 billion and rejected a bid of ZAR 14 billion from Telkom for its 75 percent stake.
