7 Days to correct their mistake

I called Multichoice to enquire how I go about paying a box office account. They told me to create a new beneficiary from the pre approved list i.e. DSTV BOX OFFICE and enter my customer number. On receiving my statement the amount I paid has been credited to my normal DSTV account. I called to correct the issue and am told it will take 7 days to correct the issue. DSTV have acknowledged payment on the 3 March i.e. its in their account from this date and to transfer to their box office account it takes 7 days. This is absolutely pathetic!!!!!! So much for being a world class company. In addition their customer agents were unbudging and kept me holding listening to music for 15 min before I put the phone down. Shame on you DSTV/Multichoice. Time of call 7:30pm Sunday evening
