Telkom Package issues - no calls or data that I am paying for

Good Day. My complaint is with Telkom Mobile. I must first say that I am generally very happy with their service and I find them to generally be very helpful and their service for everything else has always impressed me. I am now battling with an issue and nobody seems to be able to resolve it. Up until the 30th of November I had a family package with them. I have 8 SIM cards for my family cell phones and also internet devices. I had the 30G with 300 minutes package. Our usage has gone up so I went to upgrade this to a bigger package. I have done this in the past with no hassles. When I went to the store on 30 Nov I was told they have changed things and first they need to change every SIM to a prepaid and then load them onto the new package, loading them back seemed to be a problem. After a while in the shop I was told it would be done by the end of the day. It wasn't. I then went back to the store 3 days later. Same story. Later I phoned the call centre, they told me it can only be done in the store. After being away I went back to the store yesterday (9 Dec). The store manager told me it would be done by the end of the day. It hasn't. Please will Hellopeter pass this review to someone senior at Telkom Mobile to resolve. I am paying for calls and Data that can't be used and will expire at the end of the month. My family member cannot use their phones unless they load more money onto them. I don't know who else to contact. They just can't seem to get this sorted.
