PLEASE call me back!

Last week I contacted the Retentions Department and discussed matching my contract upgrade to a deal offered by one of the other networks. I spoke to a lady by the name of Vusi, from the Midrand office, who took down all the info and promised to call me back the next day. She called me back, got some more info, and told me that she will call me back to finalise. This was the last I've heard of her. <br> <br> I tried phoning Retentions, and have been doing so since Monday, trying to speak to Vusi again. It's a infinite loop of being diverted from one call centre to another, leaving messages with Team Leaders or other consultants, with absolutely no success in speaking to Vusi again. I didn't receive any reference number, and other consultants don't seem aware of a existing query. <br> <br> I don't know what to do from here - can someone please assist? <br>
