Horrible company

You *******, so it's been a year since I have been trying to change my debt order date from the 15th to the last day of the month, they wanted proof of salary change so I emailed them my payslips but no one rep**** and they kept taking the money on the 15th until the 15th of June when I had no money in the account. I then called them and got banking information from a consultant and paid the payment of r329 on the 1st of July, I asked the consultant if I must send proof of payment they said no, a few days later I received alot of calls saying I am in arrears so I got the emailed address and sent the proof of payment, until now I am still being called to say that I have not paid for June so I refuse to pay anything more until someone updates me on my correct balance, every day I am called twice a day, I explain and there has been many promises about managers that will call to assist but no one calls me, I now have over 8 different emails which I emailed the proof of payment, I am more then happy to pay them but I want confirmation that my payment I did on the 1st of July was received. Every call they busy saying calls are record so go listen to your calls and see how many times I explained, acknowledge my payment and give me a correct balance and I will pay you even now. This is the most useless company who have agents that have an attitude even, your service is so ****ty and your phones lol you should be embarrassed to even sell such useless phones. I repeat I will not pay you until you acknowledge my payment via an email and if you want my email address it's *** go fetch the proof of payment and update your records. I thank you
