You have sent the courier to come collect the dstv but when the came they refused to collect the items and said that they are not going to take it and said it is not their job. Now tell me what the **** must I do now they came here twice and was very rude to me and refused to collect the dstv the courier guys are from Ram he refused to even come by the house as i even went to meet him by the road so they can come and collect. I want this cancelled ASAP as you ****ing up my credit score whoch I will be sueing you people for as this is deliberate and i hate what you people are doing and still not calling me on the times i have mentioned
