Contract restarted when Vodacom took over Nashua

I was enquiring about my upgrade on one of my numbers because I know it is due for upgrade only to my utmost disgust to be told that Vodacom restarted my contracts from day 1 when they took over in November last year from Nashua mobile. On a call to the call centre this week I was informed that my contract will now only be due for an upgrade In another years time and there was absolutely nothing they or I can do about it. so I will have had my handset and contract for almost 3 years before Vodacom will upgrade my handset. Vodacom never once sent a mail saying that as of the 1 November 2014 my contract will restart however they were quick to send out price increase letters and now I need to wait to upgrade a outdated handset for another year due to Vodacoms negligence and total disregard to there customers. In the 8 years of being a Nashua mobile customer I never once had issues with service upgrades ect. Vodacom has really disappointed me as this is no way to look after customers. Let's see if Vodacom actually respond to this complaint and try fix there mess up.... Very dissatisfied customer.
