Date Promised was not dealt with correctly

I ordered a item from takelot, after i paid for the item they send me an date for delivery 1st of December which was acceptable as i needed the item for the 2nd. on the day of purchase i phoned to confirm the date and i got written proof of the date again for the 1st. A day after at night i went to go track the product on their website and then it showed the 4th, so i sent them an email to ask why and how they are going to get it on time to me but this is where they as a company started failing me and told me lies to keep me quiet, a day before the 1st i still had no clear answer and when i phoned i was again promised that the package would be on the 1st verbally but i asked for the waybill number and courier's number and phoned them directly, they said no it will be the 4th but i could come fetch it on the 1st at their depot. So i incurred extra cost to drive from Worcester to Epping to go fetch it and now takealot wont reimburse my cost cause according to them the date was the 4th, but i have the mails that state the 1st and i was in constant communication regarding this, so now they only say sorry, which is not good enough, this whole ordeal caused me great frustration and stress cause every time i phoned they would phone me back but this also did not happen as when they phoned back i got just more lies.

I did not expect full compensation for cost incurred but at least something to show their commitment,

I have been using takealot since they opened and believed in the brand but this one occurrence have broken my trust in them.

On Saturday a lady phoned me to say she would do her best for me as she saw i have been using them for years, but instead of phoning me to tell me the outcome, a random guy send a mail.

i wonder what can i do, i think a might lodge an compliant at the Consumer Protection Commission or what else can i do, they keep trying to brush me off.
