Not allocatting payment

I made a payment on the DSTV website on Tuesday 14 July 2015 with my credit card. Their website gave me an amount of R420.07 that has to be paid. Clicked on the pay now option and it redirected me to their third party pay u and paid the amount. Received an sms that the amount was paid. Since then I tried to activate my drifta services without success spend in total of 1 hour on the phone to dstv call centre just to be told I jave to send a proof of payment. The only proof i got is the sms. I phoned pay u their third party payment company and they confirmed that they can see the payment but cannot give me a proof of payment just a reference number. Phoned nedbank were I bank. They also confirmed they can see the payment but cannot supply me a proof until DSTV cleared the money which can take up to 48 hours. Its almost 3 days now. Client service I received was shocking to say the least and their call centre keeps blaming me the customer. Everytime I phone in they also give me a different amount first it wasthos R420.07 then it was R68.87 then R425 then R388 and last time was R360.
