Bad customer service

I have been trying for days now to upgrade my companies 3 laptops . Our contracts expired and would like to just get data plan contracts, but there is no customer service. I have phoned so many different numbers as nobody can help me and keeps giving me another number to call. Wasting hours on the phone and still no results its like Vodacom doesn't want the business. How hard is it to get data plans on existing contracts?<br> very disappointed in the customer service.
