Worst service possible

I have been battling with Vodacom for about 2 years to get the speed on my fibre upgraded. Every time I phone and they hear it is an upgrade, not a new sale, they never get back to me as there is obviously no commission involved and this has happened at least 6 times. I am having problems with my router and decided I must get a new router and upgrade the speed. This has been going on since 24 April 2023. I have phoned a few times and every time I get told that the system says there is a router in the warehouse that has to be delivered but they don't know when it will be done and they will escalate the problem. I spoke to Vodacom fibre again this morning and got the same answer. As I said to the consultant who spoke to me I have been a customer of Vodacom with the same cell number for 18 years, I have had the fibre line for +- 6 years and never have I not paid my account so why must I keep on tolerating this absolute poor service. I hope that somebody at Vodacom will respond to this message but I will not bet on it. Should somebody at Vodacom have the common courtesy to contact me the reference number is SR***. If I could give negative stars I would have done so.
