Now I must pay more since you dropped the ball again and again and again Vodacom???

So this morning the saga continues... The vodashop who could help me with my phone contacted me. Turns out the new deals are out at vodacom... They are now R100 more per month. I had already agreed to take a knock and pay R200 more than what was promissed by a store clerk in Eastgate but R300!!! NO ****ING WAY!!!! I tried to cancel my online order(Saturday the 4th of May) that was supposed to have been delivered to me on the 25th of April... They cannot do that on a Saturday... "Only on Monday and it takes 24 Hours to cancel it." I recieved a call on Monday to ask if I wanted to cancel and I said "YES". Then later that day I called to find out if anything had been done and guess what, Nothing. so i asked to CANCEL MY ORDER AGAIN!!! Letsego said she stood next to her manager when the cancellation mail was sent. Yesterday I called again and it was still NOT cancelled.... So today I must pay more...**** that! and it is still not cancelled... So since Saturday the 4th of May vodacom has not been able to cancel an order. How are you still trading????@vodacom
