worst service ever

I would like to bring to your attention the lack of service received from your carnival mall branch. In November 2019 I went into the store to get a quote for my sons stationery(attached). The store was quite but I was advised by Mbali Maseko that they will email me a quote. The quote was never sent to me so I decided to go into the branch again on the 17 December. Upon arrival at the branch I was told that they had prepared my order but could not find the box in which it had been packed in. I was then told to come back the following day to collect my order. Mbali had also quoted me R806.30 which is written by her in the attached request. I then returned to the store on the 18 December for the third time, this time hoping to collect my order, pay for it and leave. I then received a box and decided to check that all the items were in it as per the list and only found half of the requested items. When I asked Mbali what’s going on as I cannot keep going back and forth, I was given ridiculous responses like ”I did not pack the box” and stuff like that. I then raised this matter with Thabo who is the manager. He then asked the staff to gather the remaining items whilst I wait. Eventually I received all my items but this time was charged R1490.00 which I find totally ********* and unacceptable. I received the quote from Mbali which is written by her so why should I pay R1490? I then left the store highly annoyed. I had to go back and forth approximately 60km only to be quoted incorrectly by your staff.
