How To Order Mini Box Big Button Remote

This is my first post here and I haven't found a clear answer to my question, so please let me know if there's a post somewhere that covers this.

We recently ordered 2 Mini Boxes and after using a Sony RM-EZ4 universal remote with our standard cable TVs for years, the tiny number buttons on the URC 3220 remotes are simply too small for older people in our house to use. After some research I found the URC 4220 RF remote which looks perfect. Does anyone know how I can get one or two of the URC 4220 RF remotes?

Unfortunately after 3 separate chats with Cox online support, we have 4 more remotes that are not the URC 4220 RF and I'm lost as to how to get them. I was very clear when I asked the online support rep each time, mentioning that if we can't get the URC 4220 RF, that we don't want anything else. I was assured each time that I would receive at least one URC 4220 RF. What we received over the course of a couple weeks and 3 separate online chats was: one empty box (sealed and not damaged when we received it), 2 of the RT-SR50, and 2 of the 3220 RF. 

The RT-SR50 are as big as a brick and not practical, but they will have to do if we can't get the URC 4220 RF. The 3220 RF are identical to the ones that came with the mini boxes. 

I should also mention that my local Cox store said they don't carry remotes and referred me to check online. Since the online chat obviously can't help me, can anyone here? I would really appreciate any help I can get.
