Poor resolving of Query

I decided not to take a new phone on my contract, but to take a 3-gig contract at the end of October. When 1 November came, I am suddenly on Smart L. I went to the store and explained. When I opened my Vodacom app, the agent said a not to look there. She did the *111*502# and, the balance was as I explained. Then it was said I waited too long, I must wait for December, and it will be correct. I phoned 082 111 Monday 30 November and did the enquiry again. The agent said it would be correct for 2 December. This morning did a check. Still not, correct. A call that costed me R8.00 I called again yesterday. The agent said on their system I am on 3 Gig. I asked him to listen to me. The I know the system shows 3gig. My phone's balance and data shows smart l. I was transferred after I got cross and it ended in me screaming, the person understood my query. She would escalate this and some will contact me. This morning still the same, no one called me My sister and I did the same contract same day and hers are correct. Vodacom's resolving of query is PATHETIC!
