terrible service and assistance With vodacom!

I asked vodacom for a settlement on my contract and they gave me an amount which was paid 6th of march 2020. I struggle to get hold of the call center to confirm if this amount was paid and after logging my complaint someone called me to state it has been paid all is in order. I received an email on the 8th of April stating i need to pay R249. I sent an email to find out about that amount and only got an update today 15 april because i sent an email again 15 april. They called me telling me i got a ipad which the consultant herself was not sure about and telling me its a separate contract. I dont understand how can they not see the total amount to pay if a client request a settlement on a contract. I am still waiting for someone with full information to me because this is the worse ever!
