I got a cellphone contract with Cell C. Most of the times especially when I'm at work, my phone is always "Searching For Network". This is really frustrating as I could be missing out on very important phone calls. Cell C itself could not get hold of me regarding a query I had logged with them despite the fact that my cellphone is always on!!
I got another cellphone contract with Vodacom and I never experience any signal problems!
Here's another complaint with a similar problem:
Cell C please sort this out!!
