Vodacom, unacceptable service...

On Friday night my upgraded contract (400gb to 1tb) did switch over from old to new when the old data finished. I called vodacom. They couldn't see a problem. I spent at least an hour on the phone with the call center agent, switching off and on the router. They eventually told me that there was nothing they could do and that I needed to go back to ChatzConnect Vodacom. I called the salesperson in Saturday morning. He said that he would speak to his people at the store to fix the problem. After several calls and promises to call back, I went to the store. It was like walking into home affairs, only apologies no resolutions. Eventually they called their regional manager Daniel Bester who was as cold as ice in winter. He said that he could "offer" me 10 gb data for free until they solved the problems. I explained that we use at least 25gb per day seeing that my Girls are writing exams including 1 in matric. He (Daniel Bester) then very reluctantly offered to "help" me with extra 10 gb until the problem was resolved and if I didn't accept it the only other resolution would be to cancel my contract. I refused to accept that I had to pay for vodacom's incompetence. I left the router and Sim card at the Chatzconnect store with a clearly unphased and relieved salesperson. I then went to another vodacom store at Westgate. I explained my situation to them and they were appalled at the service and called the salesperson, threatening to report him if he didn't resolve this issue. I went back to the chatzconnect store. They did a Sim swop which I had to wait 4 hours to activate. This was now 19h00. I replaced the Sim, started up the router and was faced with the exact same problem, I COULD NOT CONNECT TO THE INTERNET!. I phoned vodacom again, and was asked ALL the security, profile questions for the 34th time - after ending the call with another unsuccessful attempt at a resolution, another agent phoned me at about 22h00. It was after 23h00 when we ended that call without a resolution. It had now been a full 24hours that this problem existed with no resolution in sight. The agent promised to log a call to another department and call me in the morning at 05h30. He kept his promise and called. I had to remind him that he told me that the depth he logged a call with only operated Monday to Friday and that it was Sunday morning. He asked me to check if there were any changes with the router - there were none. By now I had used up all my Telkom airtime and my wife's airtime and data as well, this situation needs to be escalated to the HIGHEST management at vodacom. There lack of understanding of their own products and none existence of appreciation of a customer only says that VODACOM DOES NOT CARE IF THEY LOSE A SINGLE CUSTOMER, because there are other customers they can target. I still cannot connect to the internet and have to buy data. Unacceptable vodacom, Unacceptable!!!
