Vodacom fails in service to loyal customers

I have been a loyal client for the past 20 years. My contract ended August 2018, I opted not to upgrade at the time. This year around April a consultant called and i told them the package I was on was too high and was considering moving to another package. The consultant downgraded my package but so low that I have to top up every week for data and airtime even though I had explained my consumption usage to the consultant. I now go into the store and told I can migrate to a higher package but cannot get another device. After 20 years of loyalty to a brand its time to move onto another provider who will value me as a client. The consultant had not even explained this important piece of info on the phone, I never even received an email with the new contract. Extremely disappointed in Vodacom and the service received. I also have an additional wifi router, when these contracts end so will my subscription for your products.
