****med by Vodacom

Vodacom called to say they want to reduce my three contracts installment with R150 each. After the agreement, I received an sms informing me that I renewed my contract and deductions will be R2426. 60. Before this call from them, I paid R1461. 28 for my contract. They made me renew my contract without my knowledge. I will appreciate if I can get help with this and Vodacom need to refund all the money they deducted without my permission. CLAUDIA.
