Distgusting Service

I am extremely appauled and utterly disgusted in the company and the way they treat their customers...On the 1 february 2021 I went on their site to purchase flowers and had R800 in vouchers and the website crashed saying "oops Harold broke it" and I need to make contact with the Call Centre but it was closed and I waited till the next day and called the call centre I guy by the name of Stebo assisted me and told me that he will log my query and call me back the following day,I also reminded him that my vouchers are going to expire and I asked him specifically will I still be able to make use of my vouchers? Stebo then said yes and I confirmed again he agreed and ended the call.That same day he called me back and told me he is going to email me and I must just respond with the voucher codes and he will sort it out for me. I rep**** and asked him how this will take he said he will call me as soon as the vouchers are clear to be used again and I waited.Stebo then called me on the 3rd February saying that my vouchers are clear and that I can go ahead and I can finalise my purchase or must he finalise it on his side I said no I will because there is still an amount I need to pay in.I then asked the question again is the vouchers still valid and he rep**** yes as I also told him that a few of them expired the day before he said yes, he will remove my order and let me know when I can go online and make my purchase and I was happy and ended the call.....I waited till Friday as I didnt hear anything from him and called in to confirm if I can go online to make my purchase and got through to Stebo who pretended that he didnt know anything about my call until I said that I was emailed from the agent he confirmed the email address and then confessed it was him...when I said im still waiting for the call to know if I can do my purchase all I got was oh sorry which was very disgusting and I was shocked at his response...anyway I went online my purchase was still there and I tried using my vouchers and the website gave me an error then I called back and spoke to Kim and she confirms that if your voucher exspires you cannot use it again...I was livid and explained everything to her and she logged a query for a manager to call me back...later that day A manager by the name of Charles called me and I had to explain everything to him because he was to lazy to find why he had to call me totally disappointed ,disgusted and appaled by the way he traeted the query he then said he will call me back after he did his investigation...he called 3 times that day and finally he assured me that the query will be sorted and I will be able to finalised mt purchase...A week went by and Charles called me on the Friday only to tell me some bull **** story starting with he has bad news and that I have to wait till after Valentines day to be sorted as the vouchers are from another company and he must wait on them never mind the fact that it was Netflorist site that crashed on me...he totally shifted the blame but never the less says that its not something we can not sort out I said ok he must call me back on the 15th February before 12 as I am also working...Charles said no problem he will make a note on his calender to call me at 9:00Am...So I waited and no surprise no call came from Charles I waited till 12:00 then called in again only to find out that Charles is not in today...WOw what are these people doing does Customer service mean nothing anymore????for such a big company....what is happening Netflorist only takes your money and dont care about their customer who complains really disgusted and disappointed I NEED HAROLD TO CALL ME BACK ASAP!!!!
