Bad Customer Service

This is my 2nd month with Supersonic and I am already frustrated, just when I thought my life would be easier with them. So I chose them an my ISP for fibre at home obviously via Vuma and this is my second month with them. When I paid the first time I didn't have issues and now they have deactivated my account for something which was their fault. I chose a 28 day voucher and they decided to choose the debit option which I also don't mind. Now I bought my 28 day voucher for the month of November, called to let them know and sent proof of payment so they could activate but still no luck. I have been calling them since yesterday (04 November ) and all they keep telling me is that they will escalate the matter. I called again today, three times and they told me the same thing yet they have my proof of purchase. I am very upset because I kept my end of the deal and all they have to do is deactivate my account!!!
