Vodacom - Shocking Service

My contract was due to be renewed in April. After a call from a sales representative early March I upgraded my contract, however I received a Huawei phone which was unable to access Google, which I wasn't made aware of. The same day my phone was delivered (within 2 days) I contacted Vodacom to collect the phone so I can renew my contract for another phone, as I wasn't given all the information when I upgraded. 2 months have now passed....After phoning Vodacom, chatting online with a consultant and even going onto their Facebook page, the phone was only collected after 6 weeks. It has now been 2 months and I still have not received any communication from Vodacom regarding my new phone upgrade. The service has been unbelievably ridiculous, I have spent more time phoning and trying to get everything sorted than I ever thought possible. I cannot believe the shocking service received. I am still waiting for a call back from Vodacom, and everytime I have to recount the entire story, as nothing is clearly kept on file. I am not one to moan and complain and this is my first review on hello peter, but I am stumped as to how to get this fixed. I often haven't even received a reference number, or there is no record of it when I try and follow up...Vodacom - this is my last try - please can somebody sort this out!!
