sick of their incompitance & you can cancel it

Two things.... 1st I went into the store couple of months ago to ask to change my wifi to a top up cause my kids use it. After receiving a bill of almost R3000 I phoned in to find out why and the said to me its never been changed on the system. I was furious because that's the reason I asked for a top up. Secondly I went in middle November to change my package and they upgraded me. I was on a smart M package with 3 gigs. I wanted more data (5gigs) as well as change It to top up. The manager of the store helped me and said it will only take place from December as its already the middle of Nov. December I decided to check my data balance and I was already using out of bundle rates cause the never gave me the 5gigs. I was still on the 3 gigs and when I once again phoned in they said they have no idea why not but it will be from January. I sent an email complaining and got a reply asking for my number. Till today nobody phoned me. You can take your contract and shove it. I am done with Vodacom and their incompitance. I will not pay that money as I spesifically asked for these things and it just never gets done.
