VODACOM ON LINE CUSTOMER CARE SERVICE SLACKS

I called Vodacom online upgrade center in October 2019, they committed to a deal for me and because of the pricing i upgraded 2 more lines, 3 days later they called me to say they cant give me the deal they mentioned to me and the 2 added lines i upgraded have been proceed, so basically i got nailed for nothing and committed for 2 years and its my tough luck. Now in November i called again for upgrades on my 2 lines and they say they cant do any deal match and wish to charge me more then i am paying and willing offer me less benefits on my contracts. i told the consultant to please do a deal match for me and assist me as i am loyal client for around 9 years and they said sorry "nothing we can do and i need shop around and if i find a deal i can call them", like really i must go back to a company that does not go extra mile to assist loyal clients and are willing to loose clients just because they cant offer services to keep clients on there base. The 2 worse parts are that they added 10GB to my contract since October month 2 month and i must pay for it and the false promises they make just to get deals on there name and added commission. Vodacom- you guys are truly lacking in service and customer support.
