Horrible Terrible Service !!!!!!!!

The worst service provider i have ever dealt with. I cannot believe this is the service they provide their clients. Last week they advise me they are the service provider but are link with MTN. I've been with them only a month and half, only experienced horrible Horrible service. last week they switch it off for 3 Days, can you imagen, some of us are working from home. Last week they advise the complex will be switch off due to none payment!!! BULL**** we only pay Linteg and not MTN . If MTN and Linteg have an agreement they need to resolved this issues between the two services provides to get the bills sorted out. WE don't ever in your life pay two service providers. When i phone Linteg they advise me its MTN , when i phone MTN they advise me its Linteg, what bull**** is this?? GET THIS SORTED OUT ASAP
