I am suffering because of incompetences at Multichoice

I am tired of the treatment I am receiving from this company. I make payments electronically every month but in some months they will stop my services and claim to not have received the payment.

I need to send proof of payments for them to resume the service. Between 15 Dec 18 to now I have called them 3 times to restore the service. they restored the services last week after I sent the proof of payment and today they terminated it again stating that I did not pay
