bad customer service

last week friday my business contract phone was switched off i contacted vodacom and they told me its because the bill wasnt payed i did not recieve a bill from vodacom so how do i know what amount to pay , they told me telephonically how much is outstanding and i payed via eft on monday i recieved a sms telling me they have recieved my payment i called them to switch my phone on they told me to switch off my cell and reboot which i did and my phone is still off , i tried yesterday again and i called vodacom numerous times and they just kept telling me to switch off and on again , up until now my phone is still off , i have called vodacom and they still giving me the same story to switch the phone off and on , this is unacceptable as this is a business phone and i cannot do business without it . i have been a loyal vodacom customer for years
