Plain bad customer service

If I could I would give them no stars. I signed a 24 month LTE mobile WiFi contract in December 2017. First few months ok. Did not like the fact that you need to request top ups of data but accepted that they did not have a system where you could do yourself like other companies. I have had none stop issues with them on and off for the year. This week the last straw is I asked for a top up on Friday evening and accepted that I would probably only get this on Saturday morning as they say they cannot promise immediate top ups so they have an average of 12 hours to do top ups This time on Friday I get email saying they have problems with their top up system. Well by Saturday just after 12 I get emailed to say they still have problems. Well now Sunday evening 18:35, still not top up and no feedback from them regarding when I can expect this. Cannot wait to get out of this contract and if I had the money I would buy myself out of this contract and go to another company.
