Vodacom and their incompetence

I have never had a more harrowing experience or poorer service from a company before. I've been back and forth with Vodacom simply trying to arrange a 3rd party delivery for an upgrade that was processed last week. So far i have been on hold for the last two days getting passed from department to department without warning or having requested it. This ordeal began with an error Vodacom made regarding the authorisation for said delivery. Upon pointing out this error nothing has been done as yet despite multiple empty promises of rectification. I have even written this entire review while on hold waiting once again to try get answers. Having reached my wits end I asked simply to cancel the contract and upgrade as why would one want to give any of their hard earned money to a company that clearly doesn't care enough to simply rectify mistakes and offers absolutely nothing by way of apology. I have lost at least 6 hours of productivity trying to rectify an error made by this damn company. I honestly just want out. After 15 years of loyalty I surely thought our business would be more valued than this. LET ME OUT PLEASE!!!
