Phoneless for 5 day, no one wants to assist!

I cancelled and paid up my contact to take effect 1 March 2016, which it did. The cancellations dept and call center both confirmed this. The problem came when my phone stopped working and I purchased a new one the sim swap wouldn't take effect. The call center can't do it on their side, it kept giving them an error. Went to Vodacom in Bayside Mall 3 times this week and won't assist me. Keep saying they can't do anything its the call center's responsibility. The store claims the contract is still running and was never cancelled. This is absolutely ridiculous after being a Vodacom customer for 12 years. Not only that I've been without a working phone since the 6th of March and my daily activities has been brought on hold. I urgently need assistance!<br> <br> All i want is for the sim swap to be done so i can go on with my life.<br> Ps: the number below wont work because of the lack of cooperation. <br> Your speedy reply will be much appreciated!
