Vodacom disappoints loyal customer (15 years+)

It's been a month since I complained to HelloPeter regarding the pathetic service received from Vodacom and the Vodacom HelloPeter called me to resolve the issue, but till date I've received no progress nor feedback as requested.

My complaint was as follows: "called Vodacom to cancel my contract on 4th June '19, and the Retentions department convinced me to upgrade. My consultant Nosipho gave me a really deal - Samsung Galaxy Note 9, Midnight Black, 400 free minutes and 900mb and she added a promotional 5GB for the 24 month contract period. Refer to attached confirmation dated 4th June '19. Delivery was confirmed and scheduled for 13th June '19 latest. On the 14th June, I called the Retentions Department to enquire as to why the phone was not delivered as promised and I was informed that there was no stock in the colour I ordered (Midnight Black). Hence, I gave the go ahead to change to Artisan Copper (Refer to attached confirmation dated 14th June '19) and requested urgent delivery as it was long overdue. During the part 3 weeks (18th June - 4th July), I have contacted various Vodacom departments (Retentions, Upgrades and Customer Care) numerous times and I have been getting different responses from all - my contract has been cancelled as there is no stock on phone, delivery will be delayed, phone is discontinued by Samsung, I should choose a different phone, my package deal is no longer valid for the same price, etc. The final feedback from Vodacom is they have cancelled the contract they committed to deliver without informing me, but willing to compensate by signing on an equivalent phone, ie. S10+ on the same package deal for R999."
