VODACOM AGAIN

Vodacom is at it again. Did an upgrade for my home internet. The offer was for internet with a Vodacom router but the consultant insisted the Huawei router was much better also comes with a backup battery just like the Vodacom router, so we took it. Once the internet was activated we tried the router and it was and still is very bad. We can't connect to the internet at all. We have made numerous calls but we get sent from department to department with no one being able to assist. On the 3rd June an investigation was logged and they said they will listen to the call we had with the upgrade's consultant and give us feedback in 5 to 7days. Today is the 7th day and after 3 calls we still have no actual answers. We were told pending the investigation the Huawei router will have to be picked up which should take 7 working days and then to issue the correct router will take a further 7 working days. We were told a senior will call but I highly doubt that will happen. I am paying R399 for something I can't use. I am a long standing customer who's bill is plays paid on time. Very disappointed.
