Vodacom account deactivation

On the 27th of February Vodacom just deactivated my contract with 3 active lines. No sms, or email or call. I could not get hold of Vodacom trough any of their channels availible. On the landline the app didnot recognise my number, tobi also didnt recognise my number. was locked out of the Vodacom app on my phone.... finally got hold of Vodacom on Tuesday, they cant give any turn around time 24hour to one month!!! Just said Vodacom is aware that some lines has been deactivated and are working on the problem??? 30 years with Vodacom...not right...but they can tell you how much you must pay monthly....this mases me wonder..
