Vitality refuses to pay fitness device cash back despite having authorised it

Frustrated as I pay for Vitality, do not get the benefits, and when I try to cancel I get red tape. Contacted Vitality & requested the wi code to buy the fitness device, and confirmed the Healthy gear card number. 24 June 2020 bought the Huawei Pro band 3 fitness device, at Sportmans Warehouse, used the correct Wi code & the correct Healthy gear card number at Sportsman’s warehouse. The cash back was never paid even though I Logged query & was told that my purchase does not qualify, no explanation given. On further enquiry it turned out SportmanWarehouse gave Vitality the wrong Healthy gear card number. Turned out Vitality doesn’t want to pay the cash back even though the error was between them & SportmanWarehouse. I did everything by the book & error was not on my side. I emailed the invoice so many times & confirmed the Vitality Healthy gear card number, but up to now not even a formal feedback. I then decided to cancel Vitality as I am paying R400 for no benefit as queries are not resolved. Have been calling since end of October, each time I am told I need 30 days’ notice, the 30 days lapse but they still deduct R400 for Vitality from my account. 30 Nov – Spoke to Brendan, promised to escalate & provide more details regarding my cash back & also cancel my Vitality as I was dissatisfied with the service. After that he went quite, no feedback EVER from him. Tried to call & asked for him never available. 30 Nov & 31 Dec 2020– Full Vitality deduction went through despite my numerous calls to cancel. 30 Dec 2020, called, spoke to Lifa who promised to follow up on the cash back and the membership cancellation. Again on 07 Jan, he promised to call before Monday 11 Jan. I called 15 Jan & Lifa had forgotten to follow-up on the cancellation & the cash back query… Endless calls to Vitality for a 6 months query that will never be resolved.
