Bad Customer Service

I transferred money through PEPsend on the 18th of October 2017 but the person on the other end could not receive it on the same day because of a technical error when it was withdrawn at ABSA and when he went to Shoprite it said the number was no longer valid. I have since contacted their call centre as it was an emergency and I was told I was caller number 1377 and this week at 1700 and my problem has not been resolved
