Vodacom lack of customer support

I am making a complaint on here in the hope that someone at Vodacom reads this and actually assists me. I have 2 complaints, first complaint is that I have just upgraded my phone, confirmed with the sales adviser over the phone my address where the phone should be delivered and then my contact details. I get tracking info, only to be told by courier that the address is different (vodacom gave them a JHB landland, Ive never been based in JHB and the address has not been in use for 7 years) the courier also failed to update their system after phoning them 3 times they have now told me my upgrade will be returned. Oh and to top it off I had to settle for a phone I didnt want because Vodacom would not assist with increasing my credit limit by R2 a month... despite the fact I spend over R2500 a month with them. Pathetic!!! So now Im sitting with no phone after waiting 2 weeks for this phone to arrive. Second complaint is that I get a call last year Sept/Oct from Vodacom telling me they would like to save me some money - on one of my other numbers, that I would get more data but it would cost me less. Well my bill went up by over R300 a month. After calling in twice last year I gave up because Id just had a baby and every call I kept making kept getting either fobbed off and told they would be in touch or calls dropped after explaining the matter to at least 3 advisers as each time I was passed to the wrong department. I now have a complaint reference for this and surprise surprise Vodacom have not got back to me as they promised. I am really very frustrated with the service and professionalism with this company.
