Poor service

Vodacom service of poor standard.i do not receive my promotional data.and have to phone every month to rectify their mistake.i buy the data on their app.and i cancelled one of my lines.because i upgraded.but again poor service i rather decided to cancel the line and rather take my bussiness elsewhere.and also do not recommend this service provider to anyone.i will also just use the other line for the remainder and also move over to another sp.i cannot see why the early cansellation is exactly the same as if i would use the line till the end.but would not receive data or minutes nor would i use this service.poor poor service
