No statement, no emails, interest charged

Every month, I receive my account statement via email and pay my installment on time. The the last time I received a statement was 15 Feb 2016. I have been waiting for my statement so that I could pay as usual but none came. Yesterday I received an sms to pay my account to maintain my positive payment record and good credit, which did not contain amount. I am unable to login to the online statement viewing facility on the Edgars website and after trying to recover my login details, I do not receive the email the website says it is sending me. I then called ***and was given the amount due which I then paid.<br> Later in the day, an Edgars rep called me regarding the outstanding payment. I explained the above and she said she will email my latest statement, including a direct number for me to call. I have still not received this email. I have checked my spam folder and it is not there either. She informed me that due to the late payment I have been charged interest, which she said can be disputed due the above.<br> I contacted the call centre this morning again. The rep who helped said there is nothing she can do. I just have to wait until someone calls me. Please help resolve this
