Failed sim swop.

On the 3rd of November I went to the Telkom store in Cape Gate centre and took out a sim card deal requiring that my number be ported from Vodacom (I've had the same number for over 20 years). I was told that it could take up to 48hours for my number to be ported. Today it has been 14 days! I've been to the store 5 times, sent numerous emails (and tried calling but they dont answer phones..) I've handed the simcard (still unused) back more than once and asked to rather cancel the contract but they kept asking me to just give it two more days. I mail them daily to ask for an update but very seldom get a reply. I will have to go in AGAIN and hope to cancel this failed attempt to switch network providers. Grass is not always greener on the other side. I will stay with Vodacom.
