Poor service, Unavailable to assist.

I have been telephonically convinced to buy a Vodafone wifi router. The following chain of events followed: 1- I have been told that the delivery will take place within 7 days, but I had waited about 2 weeks, 2 - When the router was eventually delivered I had to sign for it even before I was allowed to test it's performance, 3- I could not get the router connected to either my cellphone , laptop, or I-pad and tried a whole afternoon to make contact with vodacom without success- the message I received was that they experience to many calls and I should be patient (I can only assume it was mostly complaints). 4- in the meantime I found out that the device will have an Internet connection that will be SLOWER than the LTE connection I already have - which totally nullify my intention to buy a wifi connection that would be faster?? 5 - I did sent and e-mail to vodacom to complain, because I could not get hold of them telephonically, but did not receive any call back. The way I am feeling now is to just give the device back- I'll even pay for the unfortunate delivery- as long as I do not have to keep something that is less efficient than that I already have! What a waste!
