Disgusted, disgruntled and left feeling ****med

I was so impressed with Yoco and had been waxing lyrical about them for the last 2-3 years. Not anymore. I am not one to resort to social media but after a whole month of struggling to get hold of the support team via e-mails and online 'support' helpline and calling, I went the social media route. Still no response until a week later. Another month passed and a guy called. (The call was dropped but he didn't bother to call back.) Anyways, the brief conversation was that the development team is working on it still, with no ETA. Two months later, I am still charged for transactions that I did not perform. They promised to refund us but still nothing to date; I am looking at another service provider as I have lost faith in a company that have no accountability nor respect for overpaying customers.
