Tikona — Plan change request not fulfilled

These guys reduced their tarrif and also increased its Gbs but kept collecting higher amount from me . I was paying rs 472 per month for 100gbs of 10mbps but now they have a plan of 15mbps unlimited. They never notified me.
Now i have logged plan change request 1-[protected] on 19th June and they promised to change it within 48 hours but it is not processed.
