No signal frequently

It seems there is a problem with your services and it is getting me frustrated and affecting my job. From last week until today I have been struggling with signal and as I am typing this review I am unable to contact even Vodacom, because we have no signal. When it seems that the signal has returned, I try and make a call it does not even ring and then the signal is gone again. And it is not my phone that is the problem. My other two business phones is also not working. And my husbands phone and several other people that is working and staying around here. All Vodacom customers. Important telephonic meeting missed today because of this ridiculous service we receive from Vodacom. I am a paying customer so fix the problem ASAP.
