Poor service

With absolute disappointment I post this. I have advised since Wednesday that I was going to post on this site but Vuma support and maintenance team don't seem to care. I have had a problem with my internet being down since Tuesday 29/05/2018. My boyfriend called on my behalf to have the matter resolved. We received a reference number 80036 at 11h44 on the 29/05/2018 and advised someone from the maintenance department would be calling to have the matter resolved. Wednesday 30/05/2018 24 hours after logging the call still no call from maintenance so we called back. We were promised someone will call us to have the matter resolved. Thursday 31/05/2018 we were now getting irritated with the lack of communication from vuma so we phoned back. We asked to speak to a manager this time as it had now been 48 hours since call was logged. We spoke to Glen a manager in the support centre. He assured me that maintenance would be contacting me in 15 minutes Well yet again that did not happen. Moving onto Friday the 01/06/2018 we called again now 72 hours after logging the call. They assured us that someone would contact us from the maintenance department as we are marked as important to be done. Upon asking why I was advised that this was outside their service level agreement. I asked what the service level agreement is for them and was advised between 24 and 48 hours. I expressed I had no confidence in the promises they make as nothing had happened in 72 hours of logging my query. They assured me that a technician would contact me before 22h00 on the 01/06/2018. Well surprise more disappointment. Saturday 02/06/2018 a and we are now 96 hours without internet connection so we called again. Agreed the conversation was not polite and easy for the receiver but was told there was no manager on duty to help me. Gave the reference number and was told that they would find out what's happening just to have the phone dropped. I called back and explained everything again after calming down. Was told by the operator that she needs to get feedback from the maintenance department. At this point I wasnt expecting much as there has been nothing up to this time. She comes back and tells me the maintenance departments number is engaged and cannot get hold of them. Not surprised in the least as they have done nothing to satisfy me as a customer the last few days. We pay our subscription every month and never have a problem, but my first problem and my experience of vuma and their maintenance department is absolutely a disgrace to customer service. I want this resolved as soon as possible along with some solution on how they will keep me as a customer because right now anyone looks better than vuma.
