Being penalized as a customer because Axxess has discontinued 8 speed line

Every day there is an issue with my internet. Since I received email that the tariffs will be increasing from R549 to R755. Now the lines suppose to be faster but more problems. This is a major increase definitely not happy about this. Why must the customer be penalized because 8 speed line is discontinued. Supposed to be charged the same price as the 8 speed line for the 10 speed line. Was paying first R499 then price increased to 549. From 549- to 755 this is ridiculous!!!
