Worst network company ever

For the last year I have had endless problems with Cell c. Had three contracts and slowly cancelling them one by one. Cell c has advised cell c phones and sales agents sell them as if they are the best thing on the market. Bought the Summit phone and can say that it honestly a piece of ****. Don't ever make use of any cell c phones. The summit only worked for two to three months. I have taken it back and would like a refund but was told they will fix or replace. I have read many comments and it seems this phone only works for about two to three months generally. The phone should be recalled and customers refunded. Cell c does not treat customers fairly and should be fined for this. Unhappy client if I could rate no star I would
