Payment Made

My first TM debit order came off on 1st April, this was reversed due to the fact I had been double billed (I was not made aware of this) and no statement has been produced. The account that was debited is budgeted for the exact amount of my debit orders. Anywho, I contacted their call centre to obtain bank details to do an EFT on the 4th, this was paid and processed on the 7th (due to the holidays). I have emailed my proof of payment, I get no reply and still receive threatening sms that my line will be cut. Please sort this out or I will return the device and cancel my contract. Amount paid was R877, I used my MSISDN as a reference and a code that was contained within the email I received from your consultant.
