Horrible customer experience for an existing client

I am an existing customer of Huge Telecoms and had made an application for a bulk sms texting facility to be added onto my account for a new business (ticket No: #245045), After sending in my application on the 17th of June 2022, I experience great difficulty in receiving response when the bulk sms facility would be installed. The numerous phones calls I made I was told would be returned to me, or the agent dealing with my case would not be in the office. Basically no-one was ever available to address the installation. After expressing my dissatisfaction a technician assisted me with the installation on the 26th of June 2022 but the facility only allows for only 10 sms to be sent which is not package I have app**** for. To date this has never been addressed and I have had to resort to an alternative service for the Bulk sms texting for my business.

I subsequent to that requested a new add-inline telephone line (ticket number#247716)on the 28th of June 2022 for the new business I recently started which was successfully approved, however following the approval no contact was made to me as customer regarding when the device would be delivered and installed. Despite numerous phone calls to try follow up on the matter I was continuously put on hold, told they would look into the matter and an agent would call me back. No one ever returned my calls. A week later 6th of July 2022 I sent and email expressing my dissatisfaction of their service which eventually someone responded to. The device was delivered on the 7th of July 2022 but following installation the device has been unable to make outgoing calls. I again made numerous phone calls Huge Telecom to report this issue and was again told someone would contact me but never did. On the 11th of July 2022 I sent and email requesting my matter be addressed and received response that technicians are working on the issue. Today is going on 3 weeks since I made the application for this line and still I do not have a functioning device. This is sadly impacting my new business negatively and what makes matters worse is that I am an existing client of theirs using this same facility in my other store. I honestly thought I would have a good customer experience given my history with Huge telecoms but I am at a point I am going to cancel both my lines and find an alternative service provider.
