Absolutely Pathetic Service

First of all it started at the Vodacom shop at north gate. Went to buy a samsung tab s which was in there February pamphlet, no stock, was told they could order me one, which never happened. Then i settled for the tab 4 and when i Wanted to add the new contract to my existing contract, i was declined. I was told it was due to a contract from about 10 years ago. Was give a number to speak to collections. Well when i call them, they say they cant help, i must speak to accounts and they would transfer me. Well i ended up at the customer care who then said they cant help and transferred me to the accounts, which said there was nothing wrong with my account but couldn't see old accounts, i needed to speak to collections. They offered to transfer me and i landed up at upgrades who said they couldn't help, i must speak to acquisition. By then i had enough and was not willing to waist my time( Over a half an hour) on a company that was ***********. I want service, Vodacom is that to much to ask?
