Terrible Data Signal & Service from Cell C

I've purchased a prepaid data bundle on the cell c home connector promotion and found that the signal constantly drops at least twice a day. Have to keep calling the cell c support team every time this happens for them to reset some sort of settings on their end before the signal picks up again. I've also spoken to their support manager by the name of Themba who promised a solution for a permanent fix within 24 hours...It's now day 3 and no call from their support team. Really disgusted by the quality of the package and their customer service competency.
