Vumatel not bothered with customer service

Hardware belonging to Vumatel and installed on my premises failed on 20 March 2018, and was reported to my ISP on the day, as per support requirements. They were in turn instructed by Vumatel top log a support ticket, which they did.

By 29 March my ISP informed me that Vumatel closed the ticket, without even making contact with me. A new ticket was logged with Vumatel.

Enquiry emails I sent to Vumatel on 4 and 12 April were ignored.

After following up telephonically, Duane from Vumatel contacted me on 13 April at 15H25 and promised to have a technician at my house by 16H00 to fix the issue. Nobody came.

On 14 April I spoke to Page at Vumatel support, who escalated the query to support services.

Duane again contacted me at 10H56 and promised to send a technician by 12H00. Nobody came.

To date, I have not had any contact from Vumatel, who is incapable of maintaining their end of a service contract.

Poor show, Vumatel! When will this be resolved? All you need to do is swap out a power adapter, how difficult can that be!?
