No help from Vodacom shop staff

I went into the Vodacom shop at the Brackenfell Hyper to get a new SIM card for a new phone. The staff member there told me I need to get an affidavit to do a SIM swap to keep my old number. I went next door to Pick n' Pay, bought a SIM, had it RICA'd--they even helped me instal it in the new phone--called 136 and had the SIM swap done. Are your staff trained to be so unhelpful? Or are they merely stupid and ***********? Either way, it reflects no credit on Vodacom as a company, and I certainly will not be recommending Vodacom to anyone any time soon.
