Bad Service Vodacom

Vodacom please remove the missed payment from my credit record (listed for March). I've payed on he 30th of March as per the contract date. You, Vodacom listed it as a missed payment!!!! Please rectify I've sent mails and spoke to consultants without any success. I've mailed on the 23 April with a proof of payment to *** and 7th May. It is June and you don't assist. Going to hello Peter and the socials will help. I am patiently waiting for a rectification of the matter.
