Vodacom reply on Hello Peter is as empty as their promises. R3 500 voucher still not resolved.

I have noticed that when there is a "reply" to a complaint from Vodacom, it also means nothing. My initial complaint about a voucher which was promised to me in September 2023 has still not been resolved. I was given the "it will be escalated" response so many times. My private response was that the upgrades department tried to contact me. Yes, I have a contract to be up upgraded. No, I am not going to answer questions from a Vodacom Upgrade number. If my query was with the retentions department, why is the upgrade department contacting me. I do not intend upgrading any of my contracts, due to the inept way my query was dealt with. Warning to future customers, first get the R3 500 voucher and then agree to the upgrade. Following the "The upgrades department contacted me; it was followed with the voucher will be issued at the end of October." This was my exact issue, the voucher was first promised to me mid-September, then end September and now end October. 20 odd years of being a loyal customer means nothing. I will be cancelling all my contracts as they come up for renewal. You have just lost a customer.
