Unsatisfactory service

Very unimpressed with the service I have recently received from Vodacom. I have a data contract and was supp**** with a wifi router at the start of my contract. I took my router in to Lakeside Mall, Benoni due to the battery being swollen, and was told that the turnaround time for a new battery would be a maximum of two weeks. After two weeks I have now been told that none of Vodacom's suppliers have stock of the battery, which is now on back order, and they cannot give me any estimation of how long I will have to wait for a new battery. In the meantime I am having to buy data, which is costing me a fortune. I was told that Vodacom could give me a replacement router at a cost of +- R600, which I feel is excessive considering it is not my fault that the battery for my existing router is on back order. If the battery for my router is no longer available, I would have thought Vodacom should supply me with a different router free of charge as I am on contract.

Furthermore, I was not at any stage contacted by Vodacom to inform me of the situation, I had to phone in twice to find out what is going on.
