payment allocation not done in 30 days

i am so not impressed with the service i received from Multichoice, i made a payment via their self service site and the payment does not reflect on their side due to whatever technical reasons between them and their service provide PAYU, now i had to suffer the whole month, going back and forth, sending proof of payment to a number of their agents and even went the extra mile by contacting the PAYU team to confirm and give proof of my payment, but still nothing is being done by multichoice, the payment has not being found and allocated in my account after i have spoken to so many of their agents. the sad part is i have been disconnected more than 5 times in one month as if this is my problem. what is so difficult for Multichoice to trace my payment through their finance department and statements. do we have to be so inconvenienced as customers if something goes wrong with their internet services, didn't they say its safe and secure to make payments online? really i am tired of this issue now.
