please allocate my payment

I paid the dstv on the 25 of March ...and I faxed and emailed the proof of payments and in all those proof of payments I wrote the customer number bt up until today the payment hasn't been allocated... how can they take this long to trace the payment and allocate it....and I hate the fact that they keep on suspending the service and I have to call them everyday and being told that they still tracing they payment....I mean I paid on the 25 of march .I doubt if they even checking the the emails and faxes I'm sending because the surname and the customer number is there so I just don't understand why they just cant allocate the payment.....I'm tired of this
