Loyal customer, Upgrade denied.

I’ve got an extra contract with vodacom that I’ve not been using. Had a tablet that got ****** a few years ago, sim not been used, meaning every payment received by vodacom on this line has been pure profit with no service rendered. I have been a loyal vodacom user since 2001, since my first cell phone. I’ve been making use of contracts for approximately 15 years now, with vodacom. Even though vodacom has taken these payments without rendering any service for at least two years and this line has been due for upgrade since 2016. It’s now 2019 they continue deductions but I am unable to upgrade line and I really need a device right now. Vodacom advertises to be the best network, however they are the most difficult network to join and do upgrades.
