Account in Arrears

Following a messy divorce and a huge strain on my finances, I recently had the unfortunate experience of not meeting my monthly obligations, hence my Vodacom account was in arrears for 2 months. My line was cut and called the call centre to make an arrangement to pay it off in 2 parts, with the understanding that my account will be placed on hold until paid up. This month, I received an invoice out of the blue and low and behold, I'm being charged for services I cannot access. I have a number of contracts with Vodacom and my invoice is now at R7530-92!!! When I call to query this, I was told this is standard procedure. Yes the line is locked, but the service is provided. What a bunch of ******* you are!!!! How the hell must be able to pay my arrears and the monthly instalment, which I cannot use?? I'm a single parent, with 2 children and feel like I've just been suckered. I've been loyal to Vodacom for years and this is the first time that this has happened to me. I'm really at my wits end and deeply disappointed Vodacom!!!
