Horrible service. Very frustrating and embarrassing. Slow delivery and low quality service full of technical problems, arising each week and taking weeks to get solved. I would not recommend it to anyone. I wish we could pay after the service is delivered. Now, I paid and I do not even have our organisation's shortcode running, after three weeks. Do you have a reimbursement system if one wants to withdraw from your service?
