RSA Web prefers new clients to looking after existing ones!

No real problems with the service (signal disconnects occasionally but they are quick to sort this out remotely when I open a ticket on the app), but as a long standing customer I am not sure why I am being penalised with a price increase, and a new customer (who they supply with free installation and a new router..) will be charged R126.00 a month less than I am going to be paying from April! The fact that so far they have sent 6 identical emails (even after I got hold of the chat line to ask them to please stop, the emails keep coming) to tell me of the price increase, just rubs salt into the wound! I would happily extend my contract to get the "new client" pricing, and they wouldn't have the costs of installation or a new router to factor in!
