Vodafone India — excess billing due to international data usage

Address:

Mumbai City, Maharashtra, 400067

Hi, even my dad have been fraudently charged 2, 01, 884 rs by vodafone for data roaming while he was at bahrain airport for merely half an hour. He was not informed by vodafone executive during activation of ir pack of 3500 that this pack will not work in bahrain.
Moreover my data limit was of only 19000 then why dint they cut the connection when it exceded the limit. They didnot evn send any intimation regarding the usage while he was using.
When we went to meet the appelate officer for some discount he simply refused to give any discount and told that earlier they use to give discount because there was a good profit margin but now jio has taken all their business so no discount will be provided. Wtf!! Jus bcoz jio screwed up your business vodafone ppl will get their profit by charging fraudently to their customer? Aisa kaun karta hai yaar.

If any1 have any idea how to resolve it pls cal me on [protected]
