Vodacom customer care sucks!

Horrific, shocking service and communication from Vodacom Business (ironic, considering they're in the communication industry). A week ago I phoned Vodacom to upgrade my business contract. The agent was short, impersonal and very quickly sent me documents required for me to upgrade my business contract. I provided them with the documents. I received no call back (as requested) and before I knew it, my contract was upgraded - I have no way of knowing whether the correct cell no was upgraded and whether it was upgraded to the correct package. I requested the agent to contact me regarding product specifications and colours. Also colour choices of the Samsung S6 watch that came with the upgrade. This is not a cheap contract and I was even more horrified when a week later I received a delivery of my phone and watch - both in black colours. Imagine you pay over R2000 a month for 24 months and colours are sent out randomly, without ANY paperwork/quotes whatsoever. I proceeded to phone them 4 times, each time requesting for the agent to contact me back. I even requested a call back from their team leader. Guess what? I am still waiting and sitting with a phone and a watch that I hate and no paperwork, no feedback, no follow up, no reply, no call. Shocking shocking shocking!!! What to do? They don't give a hoot about their clients. Business or personal clients.
