Bad service at Vodacom 4u Worcester

On 18/11/23 I went to Vodacom to enquire about data packages they had, I was looking for good mobile LTE contract so the sales consultant recommended that I get the 600GB LTE package, he said it even comes with a router which I told him I would not need as I would be traveling allot but he said this is apart of the contract so I had to take it. When I went home I set up the router they had given me to test the speeds and was getting a good average of 20mbps but when transferring the sim in the router to my pocket router it would not pick up any network, I then tried it in one of my older pocket routers that's Vodacom branded but still nothing happened but when put back into the router that came with the package it picked up signal and worked. I then went back to Vodacom on 23/11/23 to enquire why this was and then the sales consultant told me that this sim only worked with the router that came with the package, I told them that this was not explained to me when taking out the contract as I specifically stated that I wanted to use this data while traveling, I then told the consulted that I no longer wanted this contract as I already have fibre at home, he said there's unfortunately nothing he could do, and I would just have to keep the contract as is. This is bad customer service if he had told me in the first place that this would not be able to work in any other router, I could have looked at other options.
