Vodacom Contracts Sucks

Hello peter. I have a problem with Vodacom. Last year August I took 2 in 1 contract phones. in a very short of space both phones had problems 1 had screen damage and the other 1 did not want to charge. On the 23rd of November I took them in, and it was sent for repairs. and they never get back to me for any updates. On the 4th of January this I went to the store to find out about the devices only to find out that only 1 device came back, and they never gave any call as to inform me that the device is in store. 2 days after I noticed that the device is not charging again, took it in and asked them to cancel the contract or give me other devices as the 2 is giving problems and answer was, they can't give new devices nor cancel the contract. the only thing they can do is to send the device for repairs again. It's going to be a 3rd payment end of the month without any devices. And that is really frustrating paying for something you don't have or even use. Keeping in mind that I took out insurance on both of the devices and with every repair I need to pay an access fee. Both of the cellphones not even in used for 3 months.
