Worst after sales service ever

I signed up with Webafrica just over a month ago. They were very quick to come and install and activate the account and I had excellent connectivity until my first payment went off. One week after that I started experiences connectivity issues and slow internet speed. I logged a call on the 15 August and was told the call needs to escalated and that a technician would contact me. Three days later I followed up and was told there was no call logged on the system. The very next day I received an email and a sms stating that the call, which could not be traced on the system the day before was being closed. I contacted the service centre again and was promised that the technician would be contacting me the very next day and the problem would definitely be resolved. It is now three days sense that call and still not technician and when I try and contact the service centre which is only accessible via WhatsApp I simply just cannot be transferred to an available agent.

They were so quick to sign me up and sent about 8 emails reminding me of my first payment yet now less than a month later I am not able to resolve a simple issue of internet speed. As a matter of interest, I pay for a 40 Mbps download and 10 Mbps line yet when speed tests are run it always shows below 15 Mbps download and around 3 Mbps upload speed. Webafrica you honestly have no after sales service.
