I recharged wrongly by mobile no. With airtel payments bank. Amount was 399. My number is already having a plan of 509 and hence i cannot use 399 plan. When i asked costomer care to refund. He deined to help. What kind of poor service. It was on 6 april when i recharged for 509 plan on my airtel no. It will expire on 6 july. Now today i. E on 21st may i was trying to recharge my friend's number with a plan 399 but wrongly i recharged my number which is already having a plan of 509. Now i called costomer care to refund my 399 amount because both plans are unlimited and i cannot use the 399 plan fully.. So i asked for refund. But costomer care denied and did not refund my money.. They are not providing me the service for 399 plan. So why should i pay for the plan.
