Poor Service from Vodacom

I have been a client of vodacom for 13 years. I am a premium client and has never missed a payment on any of my 3 contracts with them. MTN offerred me a much better package, and I contacted vodacom several times to see if they cant give me a better offer. They stated i must send the proof to eliteescalations which I did, they failed to respond, I then contacted them again and the consultant stated they can give my 6gig date extra thats also with a discount, thus I will even have to pay more for my package. I am now paying 400 rand more for the same package as offered by MTN and Vodacoms counter is to increase my amount of my package with a few extra data. Seemingly this is what you get for being a 13 year loyal premium customer. I will cancel all my 3 contracts as soon as the term expires, and I will encourage any person I know to do the same.
