Trouble with my account

Firstly, i am reporting this for my dad. So this review is his experience.

This is the third month in a row that this has happend. I have an UNCAPPED ACCOUNT with Vodacom which is R1000.00 a month. But the last 3 months my debit order was R6000.00 +!!! I have called for reference numbers which they gave me but they NEVER resolve this problem OR refund me. They say because i have WIFI at home my phone automatically subscribes to stuff that gets added to my account weekly. But i NEVER have subscribed to anything. I have been checking this for 3 months, i have been calling with NO FEED BACK OR REFUND AT ALL!! I would like to have this problem resolved or i WILL end my account with VODACOM. I have been a client of vodacom SINCE 1995 and i am a RED VIP CLIENT. in all my years i have NEVER had such **** service. Please contact me on ********** to talk to me directly.

Thank you
