Appalling service from Vodacom

We have an existing business account with Vodacom. We app**** for an Add On Line (Red 3GB) in May via Vodacom's website. A consultant, Natasha Kistnasamy, from Vodacom Business Department followed up on the request. All documents requested were then mailed to her directly on 01 June 2022. On the 3rd of June, we sent a mail to follow up on the status - received a reply that the line was approved and a mail will follow with the delivery information. On the 9th of June, after having received no comms since, we followed up. No reply. On the 14th of June, we sent a follow-up mail on the follow-up mail. No reply. On the 20th of June, we sent yet another email and finally received an answer that the device has been sent via Ram Couriers. On the 5th of July 2022, the user of the device informed that all the voice minutes and allocated data were depleted. After investigating it came to light that a Red GB1 package was allocated instead of the Red GB3 package initially app**** for and approved. Once again, after sending mails in this regard twice we were informed that a mistake was made and this will be corrected, with the correct amount of voice minutes and data loaded on 1 August 2022. On 1 August, unfortunately, nothing had changed - still on the Red 1GB package. We sent various emails to Natasha, phoned enough times for Vodacom to block my number, left countless messages for Natasha for please contact us, to no avail. On the 11th of August, we finally received a call from Natasha, informing us that she has since been transferred to another department but will investigate and to give her just until the 12th of August to get back to us. Once again, no call back and no change. Finally, on the 17th of August we had enough and informed Natasha that the issue would be escalated if not sorted satisfactorily by close of business on 19 August. To this day (23 August) no email, no call, no change - the line is still on a Red 1GB package. Absolutely appalling service. I've never submitted any reviews on Hello Peter but this is just ridiculous.
