Disappointing service

I ordered a WiFi online on 22 March. 24 March the router was delivered,26 march a tech was here for installation. I followed up several times including logging a ticket via the login portal....no response

Today 2 April, another tech comes, by the way,he made it very clear to me that he was waiting at my gate for 20minutes. Nobody made an appointment so how was I supposed to know he's at the gate! Nonetheless according to him, the job card was supposed to be with him Monday 30th March but he only received this, this morning (2/4) Anyway he was done by 12h15. I phoned the 1st tech who came to 'activate ' my line. Apparently he was waiting for the 2nd tech to 'book it out '.... nothing happens

I call again @3pm, apparently he's off today and his book is not with him and he is almost home, he will call me back in 5 minutes At 15h45 I call again cos he has not called me, he's going to phone dem quick cos they knock off @4, he will call me back. It's now 4h45...no call back... no connection

Supersonic I am dealing with you, how u outsource is really your internal process n has absolutely nothing to do with me! At least respond to your customers to keep them updated. I cannot believe this is the kind of service you offer especially when you have so much competition. Supersonic is really not serious about business
