Poor service delivery with no resolution

Last week Tuesday my sim card stopped working upon trying it on different phone I figured this means the sim card is damaged and a sim swap is required I contacted the customer care line to assist with checking if the number is active and assist with a sim swap, I was advised the number is still active however sim swaps can only be done at a Telkom store direct. I visited the branch in Johannesburg CBD on Thursday and was advised the sim swap service is offline bare in mind I use this sim for business purpose and I had already lost two days with of business during these difficult times. I was referred to Carlton when I arrived there still got the same response and referred to Park Station and received the same feedback, I went back on the Friday and still couldn't action this sim swap, I was then informed that sim cards are currently unavailable hence they can not action sim swaps, I asked what solution do they have as I have lost a lot of business due to this issue to date. I went again on Monday and yesterday and still the sim swap can not be actioned, this has now cost me a lot and after I had recommended Telkom to my organization as we are embarking in the work from home journey however after this service and still not having my sim swap done I wouldn't recommend it to any one. My issue has still not been resolved after visiting several stores
