Papers delayed and poor customer communication service

Bought a car 2 months ago and everything was fine but papers got delayed I called in several times no communication was send or anything they promised to get the papers courier in 7 days but I waiting for more the 21 days .I then bought two cars again this current month which one car I am aware they papers is delayed the other its almost 9days no ,no papers no communication nothing we I tried to speak to the whatsap number they tell me to call the landline I call they landland n keep on holding for more then 20 to 30 minutes then the line dies eventually I got hold of the lady who told me the papers hasn't been issued or assigned yet I ask to speak to the previous manager or supervisor who assisted me last Allison who was not even friendly or customer orientated she just told me she will check n call me back in 20min I told her if she can recall it's not first time she just ignored and said she will call me back an hour past she didn't call I manage to call back again she didn't even want to speak to me I could hear her in the back round telling her colleagues on the phone to tell me she will call me back .I mean if this is the kind of service am getting from gobid then I require a refund for both of my cars as I can't keep on using my own money and airtime to follow up with them and why would they tell us we will receive papers in 7 days but takes longer
