Ridiculous Customer Service

I keep on having the same issue with Vodacom and its serious ridiculous and annoying. Vodacom sent me a letter early in March to advise me that my account is outstanding and that i should pay the outstanding balance immediately. I paid the amount stipulated by way of eft as directed, the very same day i did the payment i called the call center to advise them that the payment was made etc. please note that i was advised that a proof of payment was not necessary as Vodacom does recons everyday. the 25th of the month comes and my accouont is debited for the same amount of money that i had paid in R2626.26, i called Vodacom immediately and advised that this is an error and that i would like my money refunded. OBVIOUSLY NOW I HAD TO SEND THE PROOF OF PAYMENT! i was told that by the 7th of this month my money would of been in my account. its the 14th and still NOTHING! and then one of your call center agents advises me that i will only receive MY money late next week!!! Pathetic and absurd!! Really need to change my service provider!
