7 Different feedback from 3 different departments - UTTER USELESS!!!!!!

Logging this complaint on behalf of my Wife. Received an SMS stating I'm due for an upgrade. Went to the iStore to upgrade, when the sales assistant loaded the upgrade no quote was generated. They contacted the Vodacom call center and was advised to log a service request to get finance loaded on the account. Request was loaded, we where advised that it takes 24 to 48 hours for the request to be completed. Went to the Vodacom store, they confirmed that the request was loaded and definitely withing 24 hours this issue will be sorted. Request was loaded on Wednesday, it is now Friday. Phoned vodacom for an update, 1st callcenter agent phoned back and advise within 4 hours the services request will be completed. Phoned 5 hours later, call center put me through to accounting, accounting put me through to the retention department. The retention department can only see the status of the request, cannot provide any useful information. Only to be told the SLA is 7-14 working days. Can someone please do their job!!! You are quick to phone when you need something from the subscriber, but when the subscriber needs something from the service provider, you get 7 different stories and it takes forever! How can there not be any finance available on my profile if I'm currently paying for a device for 2 years and have the cleanest profile as per Vodacom/iStore and the call center. How can I finance a phone 2 years ago, not miss one payment but there is no finance available??? Please can someone do their job, that is what us subscribers are paying for. This is ridiculous!!! I want to actually give you more money but you seem to not want it, good business model!!!
