Incorrect account information

My phoned was blocked and I had to make a payment of R347 on the 1st of August. I made an Eft payment and then phoned 083 135 to confirm and to open my line. The lady I spoke to confirm payment was made a my phone was unlock later that evening.....Just to have it blocked again this morning. Trying to phone vodacom 15 times, and all they say is they will phone back or they are experiencing technical difficultly. The amount I paid also does not reflect on my statement but my statement says my balance is 0............... How useless are they!!! I phoned again and another lady spoke to me who had no clue about anything in accounts of where even to look up my information. I send proof op payment again to Vodacom but still nothing. My contract will be ending September and I will def not continue with Vodacom............shocking service.
