Contract Issuing

I'm a long time contract subscriber of Vodacom (over 10 years). In Novemeber 2017, I decided to cancel my contracts in an attempt to manage finances. However, I have now decided to go back to contract subscription is prepaid has not been practical. I've now been advised that because of a "business rule", no new contract can be issued on my line for at least 6 months. I appreciate that I cannot renew/upgrade the old cancelled contract, however, I wanted to get a new contract against this line. The call centre agent also consulted a supervisor who confirmed that nothing can be done. I feel this is extremely inconsiderate to say the least. I am now FORCED to port to a different provider because clearly Vodacom has had enough of my money and loyalty. I'm beyond disappointed in this position that Vodacom takes as it disadvantages long term subscribers like myself who've actually spend quite a lot of money over the years. Through its high tariffs, bad network connections, drop calls, missing airtime and data, I've been loyal to this brand.
