Poor service

On the 16th of June I made use of the PayU option to pay my Dstv account. According to their system, the outstanding balance was R 1098.50, which was way too much, but I still made the payment.<br> Since then, Multichoice is ckaiming that they can't locate my payment. I was asked 3 times to send proof of payment, which I did. It's now 3 weeks later and my subscription is still not active. They are still claiming that they can't locate my payment. Despite the fact that I over paid, PayU has confirmed that the payment was successful, my bank has confirmed that it has been processed on the 20th of June already.<br> They are not even willing to activate my subscription while they try to locate my payment.<br> I have done everything possible from my side to proof that the payment has been processed.<br> I am extremely frustrated and disappointed with their service.
