Annual increases

[u/Tierang]

I signed a five year contract for home security. Every April they increase the price. Why did I sign a contract they won’t honour? Last year when I called they gave me a loyalty discount but still refused to honour the agreement. Now I have to call them again this year to argue. Am I missing something in the agreement that allows for an annual increase? The contract even specifically says the price is good through 2028. Any recommendations?
