Vumatel is the worst provider ever

I've now phoned and logged 4x calls in 4 weeks with Vumatel and spoke to the same representative each time to make sure he know what I'm talking about. Each time I need to give my same details and info as the previous week with NO response. Today was the 5th call I made and I spoke to the manager.... still nothing, not even an email to tell me they know about my issue. You can't say they have bad service - you actually need any kind of service from them to mention that.
