A disaster between myself and my Debit Councellors

Good morning sir/ madam. Thank you once again for helping with Cell C. Another issue has occurred that I need assistance from you people with. On the 26th of each month I have paid my amount of 1200 to these Debit Councellors the sms I received by shows that they have debited for March and April 2018 on the 26. However I read the email they sent me saying they did not receive any payment for these 2 months. Should I get a bank statement to check if things are in order before sending it to you people ? That's the only proof I have at the momeñt that I payed them. Kind Regards Yolanda Petersen.
