Vodacom Wtbank Repairs

I have bought a Samsung S20 cell phone during the lockdown period and was only able to book it back for faulty/ repair when the embargo was lifted ( 2 Months ) later ,subsequently the repairs can not even supply me with a date for the parts required, hence my request after another 21days without the phone for a replacement. This is surely part of the policy which they do not honour . Any assistance in this regard will be appreciated.
