Try to Topup my data on my business data LTE package

<p>Today is the second time that I tried to update mu business LTE package with Vodacom. When I app**** for the data contract the salesman said it is easy to do a top up, just register on the internet an follow the easy steps. When I do that the option I got is I am unable to do the top up on the website I must phone ********** . I have tried the call centre staff is terrible to say the least and every time I just put the phone down. I don’t know what to do to top up my data, it should be easy but apparently not!</p>
