Frustrating experience

I was quoted around R3000 for a SkyFibre upgrade on my property. Once I accepted the quotation I immediately made a payment. Around 10 days later I was told this installation could not be done because of trees on the property. I asked numerous times for alternative suggestions to no avail. I am getting no response from either the whattsapp line or the technician who I spoke to briefly. The last few days I have been asking for a refund as well as cancelation of Letaba's services. Up until today I have not had my money refunded or even any feedback. Very frustrating and disappointing. I cannot afford to sign up with a new service provider without my refund.
