Statement error still unresolved after 3 months - no resolution

After writing a review on hellopeter on 24 August 2017, see "Statement error still unresolved after 3 months", I received a response on 29 August 2017, however this did not resolve the billing error in question.

I therefore rep**** to the response on 30 August, but am yet receive any further feedback. I therefore have no option but to write an additional review.

In response to your reply on 29 August, I understand that I am billed in arrears, however the balances you refer to are not what reflect on my statements, as mentioned in my original post the closing balance as at 20/05/2017 on my May 2017 statement was R378.41, however the opening balance on the very same date (20/05/2017) on my June 2017 statement was R599.00. This has to be incorrect as there was no movement on my account until 31/05/2017 when R599.00 was paid via debit order. I have attached the statements in question to this review.

I look forward to your prompt resolution of this matter.
