Horrible service,horrible service provider

I missed month to month payment and was made to pay double for the current month and next but still refused to load in data.I complained no one answered.went to the store in Kathu almost the whole week their system is down,they say cancel writhin 30days but what happens when their system is down the whole week.I am so angry and frustrated and I used my fuel and time to return to that poor service store .Even now refused to do manual work to refund me and cancel.I feel tortured and when I call they can’t help me refer me to the same store with system issues
