DEVICES SOFTLOCKED 4 times this month

The service at Vodacom is absolutely ridiculous!!! On the 4th Jan they debited by account with payments due to them. 2 days later I get an SMS to say that my account has been softlocked. I have dealt with the following agents and up to date had no luck in sorting the issue. To date all 3 devices are still SOFTLOCKED even though my payments are up to date. 12/01 - Spoke to Samantha who unlocked the devices. That very same evening devices were softlocked again. 20/01 - Spoke to Madelin Pillay who was going to escalate to Supervisor (Luba Balo) - No feedback after that. 21/01 - Spoke to Thembeka, I was informed that she will get Customer Aquisitions to call me as they were the only ones who can increase my credit limit. 23/01 - Went in to Tygervalley branch assisted by Natasha who could only speak to the Accounts department as I have... aco**** was gong to unlocked but this was not done. 26/01 - Called in to speak with a supervisor/manager and was given all kinds of excuses!! At this stage i want to cancel all contracts with VODACOM as i ahve paid for something that I have not received any service for! THEY HAVE BEEN IN BREACH OF THEIR CONTRACT!!! HIGHLY IRATE!!!
