I am very disappointed with the lack of communication with @OPPO SOUTH AFRICA and @MTN SOUTH AFRICA.I had seen a deal with a Reno 10 which gives you a smart watch and the R3000 take a lot voucher if you upgrade before the 31st of may. I went in on the 29th of may to do my upgrade for the device and MTN took the longest time to approve it and just by the way it was an UPGRADE so it shouldn’t need to take that long. Oppo said they would be in touch with regards to the voucher and watch. I only received my device on Saturday the 1st of June. I was told the deal would be honoured still I haven’t gotten any feedback with regards to the voucher the watched arrived on Tuesday the 11th of June. 😡😡😡why say you offer vouchers if you can’t keep up is this a marketing strategy to get buyers. I’m very upset as I’ve been an MTN customer for many years. I have more upgrades due but I don’t think I would want to deal with MTN anymore!!!Today is the 15th of June and still no news on the voucher. The guy from MTN store says the manager of oppo will contact me. I tried making contact with him no luck he doesn’t pick up my call nor reply to my text messages. The store which the upgrade was done in is the DURBAN NORTH HYPER BY THE SEA MTN.
