Vodacom / MTN which network am I on?

I am currently a vodacom customer or so I think, I have been having a problem for more than 2 weeks and it seems that vodacom is unable to sort out!

Long Story Short: - I am on a Red VIP package, - I run a service business and I have received complaints from my clients that they unable to get hold of me because as soon as they dial my number it says the number does not exist on the MTN network! Hence I have lost a lot of contracts and vodacom does not seem to care! - I had to call a dozen times, due to calls dropped! calls placed on hold! calls placed on the side and you can hear the giggles and laughter of the unprofessional call center staff! - As always they promise a 24 to 48 Hour response time, but when challenged they claim that what they mean is 24 to 48 hours, 8 hour per day which means 3 to 6 working days, so roughly up to 8 days weekend depended! But I have been waiting over 2 weeks! However, the downtime will NOT be recompensed! - Only to come to find out that my number was ported from MTN to vodacom 10 years ago, BUT it was not successful (So, can I please get my money spend with Vodacom for the past 10 years back. Since it was *******ly charged! I AM ON MTN, OR SO I THINK!)
