****ed customer

I am a loyal customer for ackermans and I will continue supporting them , my issue now is I have made payment 27th July for my account through EFT and my payment is not allocated , I start contacting them on the 1st of August after receiving an sms that I did not pay , I was asked security questions of which I did answer the questions correctly , but I kept getting the same email for the 3rd times giving them same respond , I was then told to send a proof of payment to the other department for further investigation of which I did send my account statement, I then got an email from customer service asking security questions for the 4th times, I then called and got an agent who said he can't see my pervious emails , and my documents he said I must send my documents again to customer service of which I did , and today I got an email from customer service asking me the same thing I am so annoyed because I feel like they are lazy why don't they even call me if they really want to help why the run around when they have to just allocate my payment because I do pay using the same account please intervene
