Vodacom Never Again!

I would have give Vodacom ZERO stars! We have had a top up contract with Vodacom for almost 24 months now. Every Month Vodacom Debit order + Insurance of the device goes off not one month were there a problem except for the 1st month it did not go off due to a error from Vodacom's side which they admitted was their fault! When I checked on my Vodacom App recently I noticed it is time for a upgrade... Went online to do the top-up contract online much easier as it is difficult for us to get off work. Immediately they sent a e-mail with a reference number stating that a agent from their call centre will contact us within 24 hours, otherwise we must contact their call centre and speak to consultant which I have tried but were kept on hold forever.... 3 days later I go into the vodashop to enquire why no one has contacted us yet? The lady at the shop asked for the contract cell phone number which I gave to her, she then goes on to tell me that I indeed qualify for an upgrade on this number BUT because their system shows that our debit orders has not gone through recently they will only be able to give me a "cheap" phone. When I asked her she must tell me when exactly did my debit order not go off she told me that she cannot do that but I can bring in 3 months bank statements and they can see if they will be able to give me a better phone than the very lowest on the range. I mean really if this is how Vodacom treat's their loyal paying customers, I would advise people to beware. Almost 2 years every month I have paid my account Via DEBIT ORDER I have proof there-off now they want to tell me that I can only get the cheapest phone in their range! Sorry Vodacom but then I would rather end my contract with you and move to another service provider.
