Vodacom Advanced Repair Centre - Poor service/no communication

My cellphone was received by Vodacom Advanced Repair Centre on 13/03/2024. There was a delay in the communication received form them as they had incorrectly captured both my name & email address from the store receipt. A quotation was accepted, signed & returned to them via email on 20/03/2024. On 26/03/2024 I telephoned to enquire about progress and was advised that repair was underway and I would receive SMS communication when it was ready. 2 days later on 28/03/2024 I received an SMS to inform me that my device would be returned unrepaired as I had failed to accept the quote. I immediately telephoned both the callcentre & store to clarify, to no avail, and was promised a call back within the hour to advise. 6 hrs later I received a new SMS for me to contact them with an instruction to either accept/decline my quotation. It appears that there is no communication from Vodacom or any updates made to their system when a customer gets in touch or has a query.
