Pathetic service from vodacom

I had a 36 month LTE home internet contract with Vodacom, il1 year into the contract Vodacom changed the tower from 4G to 5G. All Vodacom wanted to do was cancel the contract and move me to fibre which I didn't want. After finding out that the tower was changed over I requested Vodacom to pick up my 4G router and supply a 5G router as I'm in full 5G coverage and no 4G coverage.

And yet again Vodacom could not do this, eventually they decided to move my upgrade date forward to current so that I may upgrade to a 5G router.

However when I try to upgrade Vodacom wants an upfront payment. Why should I pay additional because of vodacoms negligence in changing the tower over, I'm already loosing out on the discount I took on my previous contact.

Vodacom dose not care about their clients or the client's needs
