Loosing a client with Vodacom for 19 years

I'm unable to upgrade as I was under debt review that has now been sorted. It amazes me that you'll take my money every month but won't upgrade me to a different package. My average spend with Vodacom is 1600, I'm pretty sure if I go to MTN they will not be as anal as Vodacom and there systems I'd like to say thank you for all the service over the years but if this is how you treating me I don't have much to say to you.
