Vodapay app not functioning as it should since its launch

The new vodapay app is not working as it should, nobody at Vodacom can help despite hours spent on the phone with them. The new vodapay app disprays "The following lines were linked on the My Vodacom app" yet it (vodapay) fails to link them. This has been going on since the launch of the new app, I have unable to monitor my accounts. Vodacom even requested my MTN number to try and supplement and resolve the non-functional vodacom to no avail.
