poor service

having a problem with my giga 200. the network is slow doesnt allow me to connect to internet properly. tried roaming on vodacom its the same. cell c is robbing customers by making them take these packages and throttling the speeds. they must reimburse me so i can buy a telkom or vodacom or mtn data bundle. worst network . also had problems with my contract previously and now prepaid. i will make sure never to recommend cell c to friends and aquaintances. phone no ********** 950
