Vodafone — vodafone no [protected]

I dropped my cheque no 448325 of ICICI BANK dated 02-06-08 in the DROP BOX of Sector 18 Noida office of Vodafone.However, on 4th of June 08 my outgoing was barred with the excuse that my usage has exceeded the limit.I was surprised and went to their office in Sector 18 Noida To my shock the payment was credited to some other customer.The mistake has been detected but even then I keep on getting the calls that I must make the intereme payment immediately to avoid disconnection.Am I using this mobile for my inconvenience!!!
