Idea Cellular — regarding upc not generated

"upc can't be generated as mobile number is not configured" is shown on return message from 1901, i tried atleast 6 times in different days and also talked customer care they once said try tommorow and next time they said server error. One more issue i am unable to change language although i successfully changed ivr language but customer care agent still talks in malayalam so i was forced to take one of my friends help although i am in kerala but still they should talk with me in either hindi or english as i know only those language and atleast these malayalam speaking guys should be effecient to have a minimal english communication. But they know only one english line which is "this is malayalam customer care please change language to english by dialing 12345" which i tried but no luck why they themselves can't redirect me english customer care. There was a porting offer of 2 month unlimited till yesterday which i missed due to the mistake of these idea people and now i am suffering.
