Bad Customer Service

Took a new contract Galaxy Tab E and was suppose to be 16Gb , but received 8gb same day 09May called Vodacom and they logged a collection, from then on when i followup wth Vodacom when RAM is collecting the consultend will say thy cant see my cancellation and we log again. Then i called again was told RAM will call to collect, i even following with RAM and when i call them they will say a consultant will call me, I would confirm my cell number and the collection address but even today 28 May i still have the Tablet no collection been calling between Vodacom and RAM to followup saying the phone its not even safe cause i drive around with it cause i dont know when thy will call, bad customer service from Both Vodacom and RAM. Vodacom don't care of their customer, the only time they are useful is when you take the contract after that you are no body to them. 25 Friday i called again and was told the same thing a consultant will call you
