Mistreated and punished loyal customer

I am a loyal customers at Vodacom for more than 17years and had up to 2020 ten different contract with Vodacom for all my close family which was on my accounts and I paid for.

2020 I had a huge struggle to cancel 3 contracts that reach the end of the contract period. Due to *********** consultants I had to get assistance on helopeter to cancel it after a 5 months struggle. I have still remaining 5 open contracts with Vodacom. Last week I tried to upgrade my main contract which end on 31st Jan 2021. To my shock I am now penalised or mistreated by Vodacom. I was unable to upgrade my contract. Their excuse was I missed a payment or have a bad payment profile! I NEVER MISSED ANY PAYMENTS IN MY 17YRS WITH VODACOM! This is a nice thank you from Vodacom. Well in that case see this as my formal notification to end this contract ***! April I will end 2 other contracts and another 1 in September 2021 and the last one in 2022! Have a Great day!
