Disgusted by INFINITEC customer service

I am disgusted with customer service for cook for life/Infinitec.i made my first payment on the 26/06/2021 with a ref no...I did not include ref before the number,I wrote there combo 3.on July 03 I paid the whole balance for combo 3. I then made the first phone call,send through the proof of payment and still nothing happened.i made a second call I was then informed they couldn't locate the payment as I did not write ref. I assume when printing any books with remembers there's is no way the numbers can repeat and the system should be able to connect the numbers if the staff fails. On the third call I was informed it was traced and they will deliver combo 3. I changed my cellphone number and I gave them my new no. I got the 1st delivery which was a wrong order after I informed them I am changing the combo I initially bought,that was in August already. The courier was sent to collect everything..I sent them back. On 30 August I received yet another wrong order and I am told i have to send everything back. I am tired and disgusted about the service I don't know whether is because the business is in Tzaneen or what..this is the WORST service I have ever received. I am annoyed and I would really appreciate my money back because I cannot keep my life on hold for Infinitec. I don't recommend people purchasing anything from this *********** company.

I would love to get a refund.
