Additional E on my accounts - someone spelling

I phoned the call center already twice - my accounts all has an additional E on next to my name. They made an error when they updated my accounts - I only have one name with starting with an R - but now on their accounts I have two initials R and E - my id is always given when I upgrade my contracts. Please vodacom how many more times do I have to request my details as being amended to what it should be? Account number: QV358528-8
